The Best 30 Gallon Fish Tanks for Stunning Underwater World

best 30 gallon fish tank

The 30 gallon fish tank is exceptional because it represents the perfect middle ground, transitioning from the beginner tank that is the 20 gallon tank and into the bigger tanks. From here on, it could be quite a challenge setting up mainly because there are not as much all-in-one kits for this size as compared to smaller ones.

This means that as you progress with the 30 gallon fish tank, you must expect to build the set-up from scratch. You must have a bit of know-how in this aspect. And you must also have the best 30 gallon fish tank your arsenal.

Buying a 30-gallon fish tank is a sizable investment for anyone. So you must evaluate every primary consideration to avoid any sense of buyer’s remorse. Here’s a look at a few of these crucial factors to help you navigate this marketplace:

  • Tank Location: Every 30-gallon fish tank will occupy significant space. Therefore, buyers must account for its weight, temperature, and lighting when designing an area. They must consider all these factors before bringing the tank into their home.
  • Construction Materials: Most 30-gallon tanks will be made from glass or acrylic. The choice between the two boils down to glass being more affordable with better viewing, while acrylic is more durable and convenient.
  • Price: Various factors will impact a 30-gallon tank’s pricing. Some include extra accessories, durability, and unique designs. For instance, a 30-gallon acrylic tank kit will cost much more than a standalone glass option. It’d be wise to account for these features when creating your budget to make this process easier.

If you’re a fan of Lowboy aquarium’s low design and willing to shell out more money, you can even order a customized one. Just note that while the quality is indeed superb, the price can be high, not to mention that the brand may decline shipment to locations that are too far for fear of breaking the tank.

If you’re getting overwhelmed with the choices available, fear not. I’ve narrowed the top-tier of the best in my list below.

High Quality 30 Gallon Fish Tank Reviews 2023

1. LANDEN 30 Gallon Rimless Tank

LANDEN’s 30 Gallon Rimless Tank consists of heavy-duty, thick glass. So buyers can rely on this product for durability that other glass tanks won’t offer.

When setting up this product, I was enthralled by its wide field of view and excellent viewing angles. In this regard, my previous 40-gallon aquarium couldn’t hold a candle to this high-end LANDEN model.

I was also delighted by this tank’s ability to adapt to almost any situation. In other words, its design can mesh with various applications, from reef tanks to aquascape purposes. There’s no reason to believe it wouldn’t hold up in all these situations.

Furthermore, it does an excellent job of livening up any room’s decor. LANDED provided it with beautiful craftsmanship, ensuring it’ll never be an eyesore. It’s a benefit that buyers wouldn’t get from any old cheap 30-gallon or 35-gallon tank for sale.

I must also offer LANDEN some praise for including a cushioning pad with each purchase. It’s a lovely addition to provide more stability to my tank’s corner areas. Plus, it saved me money on not buying a new 30-gallon tank with stand components included.

However, finding a suitable lid for this square aquarium was challenging. I wasn’t the only one to have this problem, either, as other customers often mentioned it. So anyone intending to use a lid must consider it when evaluating this model.

  • Durable construction made from thick, heavy-duty glass
  • Wide field of view offers an excellent viewing experience
  • It fits almost any situation with an adaptable design
  • Beautiful, stylish craftsmanship
  • EVA-material cushioning pad promotes stability
  • Difficult to find a suitable lid

Aside from the lid issue, this tank checked off all my boxes. It’s a durable, stylish tank that can work in almost any situation. I couldn’t ask for much else from a brand-new 30-gallon fish tank.

2. SeaClear Acrylic Aquarium Combo Set

SeaClear Acrylic 20 gal Rectangular Aquarium Combo Set

If you are searching for a reliable, spacious, and good-looking aquarium for your precious fish, perhaps you want to try the SeaClear Acrylic Aquarium Combo Set.

There are many things about this aquarium kit that impressed me a lot. First is the quality of the acrylic tank itself. I thought at first that acrylic tanks were a far cry from glass tanks. In addition, this 30 gallon freshwater tank has so many positive features that fish keepers will like.

The first is the size. This tank is really spacious, I was able to place 5 gouramis and watch them swim around graciously. My kids really like watching the fish after coming from school.

The acrylic is really durable. It can withstand multiple bumps without breaking, as opposed to a glass tank. With this, I don’t need to worry about buying another aquarium just because the kids have accidentally knocked it over. Also, if it ever happens, I know that the tank will not shatter to pieces.

The filter, on the other hand, is very remarkable. Its three-stage filtration system keeps the water clean and clear at all times. Because of this, the water is free of unwanted particles, harsh chemicals, and harmful organisms that could stain the water and make it uninhabitable. Meanwhile, the light fixture does a great job of illuminating the contents of the tank.

What I don’t appreciate about this aquarium kit is how the acrylic can get warped. Although there are no apparent leaks in my tank, warping can be easily spotted even from a distance.

  • Has an excellent filter
  • Has a 24-inch light fixture
  • Has a reflector
  • Made of acrylic
  • Lightweight
  • Durable
  • The acrylic may warp
Considering all of the information stated above, I can say that the SeaClear Acrylic Aquarium Combo Set is a remarkable product. It is very reliable, durable, and spacious. It has every accessory that a hobbyist needs: a light fixture to illuminate the contents of the tank, and a reflector to equally diffuse the light. It is also lightweight and looks very much like a glass tank. If you want to get the top-rated 30 gallon aquarium kit, this is the product that you should be looking for.

3. Coralife LED Biocube Aquarium


Whether we like it or not, aquariums with automatic features can make our lives infinitely easier, right? If you don’t mind spending money for your next 30 gallon fish tank kit, then perhaps the Coralife LED Biocube Aquarium will satisfy you.

One of the things that immediately impressed me is the sleek design. If I can be honest, I say that this one projects a masculine image. This works perfectly for me because of my two sons. The curved edges really capture attention. In addition, it commands safety and comfort. I can place this tank anywhere in my home without worrying that my kids will get hurt should they accidentally bumped their head in the tank.

The lighting scheme is another impressive feature of this fully-automated 30 gallon tank. The LED lights are programmed to mimic sunrise and sunset. This feature aims to help the fish reorient their senses and help them grow as they should in the open water. This tank has an LED hood that serves as a housing unit for the LEDs and a cover to prevent the fish from jumping out.

The filter, on the other hand, is fully submersible. What I like about the filter is it works quietly. It doesn’t vibrate wildly all of a sudden, unlike other filters in the market. In terms of performance, I have observed that it cleans water flawlessly. I can say that this filter is absolutely compatible with the tank’s fully-automated setting.

What I don’t like about this particular 30 gal fish tank kit is how it is prone to leaks. The stylish black cladding hides rather weak silicone seals behind it. One time when I was attending to other tanks, I heard a strange sound of water. I searched around only to find out that this tank was leaking. After applying an extra coating of silicone seal, the tank is now as watertight as it can be. I just wish I didn’t have to do that.

  • Sleek design
  • Has an automatic sunrise/sunset light mode timers
  • The filter is built-in
  • Filter works quietly
  • Compact and customizable filters
  • Easy to set up
  • Easy to clean
  • Durable tank
  • Prone to leaks
After evaluating the facts stated above, I can confidently say that the Coralife LED Biocube Aquarium is indeed one of the best 30 gallon fish tank kits in the market today. Truly sleek and eye-pleasing, you find it very convenient and easy to maintain. If you want an easy fishkeeping life, this is the tank kit that you should be buying.

4. Tetra Complete LED Aquarium

The Tetra Complete LED Aquarium is a 29-gallon tank coming in complete kit (power filter, heater, thermometer, etc.) is too convenient. It’s not a product worth missing out on over 1 gallon of water capacity. An excellent example of its convenience level is its easy assembly and setup processes.

I was also delighted by this product’s energy-efficient design. It offers this benefit by having a hinged hood and eco-friendly white LED lights, which reduces power consumption. Therefore, it doesn’t only keep the fish alive but also helps lower the electricity bill.

Buyers will love this product’s durable glass construction, as well. It’ll ensure this 29-gallon tank outlasts most average glass fish tanks. I don’t see why it won’t stay in tip-top shape for more than a few years without needing a replacement.

One last worthwhile feature is its ultra-quiet air pump. It keeps the noise down to a mammal to ensure I can do all my activities without constantly hearing my aquarium.

I only wish this tank’s lid didn’t contain a flimsy design. Unfortunately, the issue keeps this aquarium from being a perfect fit for my needs.

  • Convenient 29-gallon tank kit with all necessary accessories
  • Easy assembly and setup processes
  • Energy-efficient design with hinged hood and white LED lights
  • Promotes longevity via durable glass construction material
  • Maintains low noise level with ultra-quiet air pump
  • The lid is slightly flimsy.

But I can’t let a minor issue like a flimsy lid keep me from loving this practical option. The energy-efficient design and included accessories make it more than worth it. Plus, it’s easy to find a replacement lid if necessary.

Outdated Products

Aqua Culture Aquarium Starter Kit (Outdated)


When it comes to 30 gallon tanks, nothing beats the Aqua Culture Aquarium Starter Kit. With this particular product, you can be sure that you will have an easy life while fully enjoying the benefits of watching fish swim inside the tank.

Trying this 30 gallon fish tank starter kit is one of the best times of my career as a fishkeeper. It is very easy to set up and clean. I also find this tank kit easy to use. Even my twelve-year-old child will find it very simple to operate.

In terms of quality, there is nothing bad I can say about it. The tank is made of strong glass, which can tolerate multiple bumps without breaking into many pieces. The filter, on the other hand, provides top-notch performance. It is fully submersible, operates quietly, and keeps the water clean and pristine at all times. With this filter, I never have to worry about rogue particles, harsh chemicals, and harmful organisms which could contaminate the water anymore.

Meanwhile, the LED hood provides maximum protection while giving maximum comfort at the same time. With the little opening located at the corner of the hood, you don’t need to lift the whole cover. I just insert the fish food and within seconds, the fish have a full belly!

What I don’t appreciate about this tank kit is the quality of light in relation to photosynthesis. The light is so weak it cannot support live water plants. I find it disappointing because I meant to put real plants inside the tank. However, upon realizing how weak the light is, it seems that I would have to use fake plants to decorate the tank.

  • Durable glass tank
  • Filter runs quietly
  • Comes with free fish food
  • Has an LED lighting
  • Has a strong LED hood
  • The lighting is weak for real water plants
After reviewing all of the pertinent information regarding this product, I can say without hesitation that the Aqua Culture Aquarium Starter Kit, 29 Gallon is one of the best. The tank is made of durable glass, the filter operates quietly, and it has good LED lighting to illuminate the contents of the tank. If you want the top-tier 30 gallon tank for your fish collection, this product will provide you with the ideal environment for your fish to thrive.

Marineland AMLPFK29B Biowheel Aquarium Kit (Outdated)


Of all the mid-size tanks I have reviewed, this one really surprised me. Aside from being cheaper compared to other brands of similar size, this product really exceeded my expectations. If you want highly reliable 29 gallon tanks to house your beautiful fish and marine plants, then the Marineland (Aquaria) Biowheel Aquarium Kit with LED Light is the one for you.

This product has everything that I’m looking for a great aquarium. It has an amazing LED light that mimics moonlight. This is truly mesmerizing to look at. The tank is properly illuminated without straining the eyes of anyone who looks at it. Furthermore, the LEDs are housed in a hinged hood which provides great convenience. When I’m feeding the fish, all I have to do is to lift the front portion of the hood to open it, drop some fish food into the water, and close it the hood down.

Another remarkable feature of this aquarium kit is the filter. It keeps the water crystal clean and smell-free 24/7. With this filter’s mechanical filtration, I don’t need to worry about leftover fish food polluting the water. In addition, chemical filtration takes care of the nasty chemical residues which could poison the fish and turn the water foul. Biological filtration, on the other hand, prevents unwanted bacteria and fungi from thriving and taking over the ecological condition of the tank.

One thing that discourages me from completely giving this product a good 5-star rating is the difficulty of finding it online. I had to search the internet thoroughly before I could find where this product is being sold.

  • Cheaper compared to other products of the same size
  • Amazing moonlight LED
  • LED bulbs can be replaced
  • Has a hinged LED hood
  • Has an excellent filter
  • Filter operates quietly
  • Has a heater for tropical fish
  • The item description online is confusing
After weighing the pros and cons, I can say that the Marineland (Aquaria) AMLPFK29B Biowheel Aquarium Kit with LED Light is truly an amazing product. If you want to breed fish, or just simply enjoy the pleasure of watching them swim around, this is the product that I will recommend to you.

Marineland Glass Cube and Column Aquarium Tank (Outdated)


If you are tired of using the same old boring-shaped aquariums, Marineland (Aquaria) AMLNV18080 Glass Cube and Column Aquarium Tank, 27-Gallon would certainly spice things up a bit for you.

Even though this product only has the aquarium on the package, it really is a serious product for all fishkeepers. It is a cube-shaped tank that provides a classy vibe and looks. I find this very interesting since almost all of my fish tanks look the same. The design of this 27 gallon tank is very charming. It certainly draws your attention and never lets it go. Honestly, this is the tank’s greatest feature. This tank can certainly be used for decorative purposes.

Another remarkable feature of this tank is the quality of the glass. It is scratch-proof and distortion-proof, which are both important in my opinion. This way, the tank won’t easily break even if it suffers multiple bumps and scratches. There are small kids in my home that’s why these qualities are very important to me.

What I don’t appreciate about this product is the false advertisement. In the product description, the image has a cover or canopy. At first, I thought that this was an additional feature. However, I was really shocked to learn that the product was just the tank itself. I hope that the company just post the picture of an empty tank instead to prevent luring hopeful hobbyists.

  • The cube shape provides a classy look and vibe
  • Made of scratch-proof and distortion-proof glass
  • Comes in black
  • Aesthetically pleasing
  • The lid is not included in the product as included in the website
After giving all of the important facts careful consideration, I can safely assume that Marineland (Aquaria) Glass Cube and Column Aquarium Tank is an outstanding product. The tank is classy-looking, attracts attention, and most of all, made of durable materials. This can be used to decorate any space inside or outside your house. If you want to house your favorite fish with a good-quality tank, this product should be on top of your shopping list

Fluval Accent Glass Aquarium (Outdated)


If you want a fully automated filter that can help you not only clean the water, but also help you drain the water easily, the Fluval Accent Glass Aquarium, 25-Gallon is the high-quality product for you. It uses the latest technology that will help you have an easy time taking care of your favorite fish.

Even though this aquarium kit is only 25 gallons, there are still so many things to get excited about. First is the amazing LED lights. This lighting feature not only illuminate the contents of the tank but also provides a decorative effect especially if strategically placed inside the house. Furthermore, the LEDs have a unique feature: it mimics daytime and nighttime light settings. This is perfect for tropical fish that you want to ensure proper environmental conditions in order to thrive.

Another thing that impressed me is the one-touch SIMPLETEC filter. One press of the button and it will clean the water and make sure that there are no standing particles, harsh chemicals, and harmful organisms that could affect the fish and plants inside the tank. Moreover, this feature can also make your life easier because it can drain the water from the tank using the same feature. Replacing the water will still need manual labor using the water bucket, though.

One thing that I do not like about this product is how the water leaks if the tank gets overfilled. I do not know about the other tanks that other customers bought but my tank surely leaked on the side. Perhaps the silicone sealing gave up and made a tiny hole that let the water through. I still have to have to investigate and patch the tank as of this writing.

  • Has its own water collection bucket (95 L/25 Gallons)
  • Has LED lighting that mimics daytime and night time settings
  • Filter employs one-touch SIMPLETEC technology for water replacement and filtration
  • Easy to set up and maintain
  • Water leaks if the tank is overfilled
In a nutshell, the Fluval Accent Glass Aquarium, 25-Gallon is indeed a fantastic product. It has outstanding LED lighting which provides a nice illumination inside the tank and decorative effect in any space it was installed. The tank is made of quality glass which can hold the pressure 25 gallons of water exert. In addition, the filter has an excellent filtration system which keeps the water clean and clear all the time. Finally, this tank kit is very easy to set up and maintain, so you can devote your time and energy to doing other important things.

Aqua Culture 29 Gallon Aquarium Starter Kit (Outdated)


Starting with your fishkeeping hobby using a mid-size tank is never easy. You need to get a reliable product that can help you get started smoothly. If you can’t choose among the many products that are sold in the market these days, the Aqua Culture 29 Gallon Aquarium Starter Kit with LED is the one you should be getting.

Here’s what makes this particular 29 gallon aquarium kit so interesting. First, the glass tank is very durable. It can withstand multiple bumps without breaking to million pieces. This tank is very ideal for my home office because I don’t have to worry about my kids knocking it down. Not to mention that the tank is very pleasing to the eyes.

Another positive feature of this 29 gallon fish tank kit is the LED. The light is not only enough to illuminate the inside of the tank, but also enough to become a beautiful decoration in any space where the aquarium is placed. Once lit at night time, anyone who is looking at the aquarium will certainly think that they are inside a submarine.

Meanwhile, the filter is another fantastic accessory of this aquarium kit. It can remove any standing dirt or large particle through its mechanical filtration. Any harmful chemicals are filtered out through its chemical filtration, while harmful organisms such as bad bacteria and fungi are kept away through biological filtration. With this filter, I can be sure that the water is always clean and clear.

While the LED lighting is indeed impressive, there is one thing that I don’t particularly like about this tank kit. I find that the light is not enough to help the water plants flourish inside the tank. Because plants cannot survive inside this tank using the stock LED light, I had to use artificial plants to make the tank look good.

  • Tank is durable
  • Aesthetically pleasing
  • Comes with free fish food
  • Filter operates quietly
  • Has an excellent LED light
  • Has a strong LED hood
  • Fish care guide included

What To Look For When Buying 30 Gallon Tank


The midsized (or average-sized, as known to some) aquariums are arguably the most known tank size in the world. Famous for its size that is perfect for those beginning in the aquarium collecting hobby, as well as the seasoned hobbyists in the scene, the midsized tanks boast versatility in a number of factors.

And right the middle of the midsize variations is the 30 gallon fish tank.

So what are you supposed to look for when buying a 30 gallon fish tank? When I was a beginner in the hobby scene, this was one of my questions as well. And as I have progressed through the years, I have a few key pointers in choosing the perfect 30 gallon aquarium for you.

The Right Placement

Unlike the case with nano fish tanks where finding the proper placement is easy as a breeze because of its small size, finding a proper placement for the 30 gallon fish tank would require a bit of planning. Since the 30 gallon tank is visibly bigger, it could cause quite a few hindrances when not placed properly.

This is where it all boils down to. Will the tank be perfect for the placing? Will its dimensions line up with the spot you have chosen? And will the material you have chosen work great with the designs and plans you have for your tank? Take time for careful consideration and deliberation regarding this, there is no rush.

There are a number of factors to consider. One of the main ones is weight. The 30 gallon tank, when filled with water (and the assorted decorations inside), can weigh anywhere upwards of 48 lbs. Because of this, the strength of the tank’s holder should be considered, as well as safety.

You should also consider the temperature as well as the location’s lighting. Because the 30 gallon tank is heavier and evidently bigger, the constant changing of the placement can prove to be tiresome.

Lastly, consider the aesthetic placement of the tank. A decorated 30 gallon tank can provide therapeutic visuals that are refreshing to the eyes, and it is a great addition to any room. Be it in a receiving area, in an office, or even in a study. Choose a spot carefully and commit to it.

The Right Dimensions

Unlike with the other, more famous tanks, the 30 gallon tank only comes with a couple of variations. First, there is the 30 gallon long tank, and then there is the 30 gallon breeder tank. They slightly differ in dimensions, the 30 gallon long tank being 36 1/4 x 12 5/8 x16 ¾, while the 30 gallon breeder tank is measured at 36 3/16 x18 1/4 x12 15/16. Both variations function the same.

The great thing about midsized aquarium tanks such as the 30 gallon fish tank, is that these tanks are easier to clean. The nitrogen cycle that occurs from inside the tank would not have as much build-up, and if it does it would take a longer time than nano tanks. Because of this, the harmful changes in the water’s chemistry would not be greatly affected. Aside from this, the 30 gallon tank is just the right size to have an average running cost, which is great news to the owner.

The Right Make

The 30 gallon tank is quite a versatile tank, and it is no surprise that it comes with a couple of variations in terms of making.

  • Glass

Glass is the classic material used in traditional tanks. One advantage it has is that it is scratch resistant. There are no wrong choices for the décor and the equipment you are to use for the tank; none of it will scratch glass so deeply that it affects the general visuals of the fish tank.

Another advantage of the glass tank is that it has rigid panels, meaning they are not likely to be dented. This speaks a lot about its general durability. It also provides less visual distortion for the tank. It is glossier and much clearer than acrylic. One of its most amazing features is that it would not turn yellow over time, which says a lot about long-term investment. It is also non-porous, and last but not least, it is an affordable option.

  • Acrylic

Acrylic is another material that is widely used in 30 gallon fish tanks. One advantage it holds over the competition is that it is lighter between the two. It is way easier to move around and lift and would also require less of the tank stand (although it would not hurt to play it safe!).

Another important advantage it has is that with the acrylic make, the shapes of the 30 gallon tanks are not limited to your plain, old version. A key advantage of the acrylic make is that it holds a better impact resistance as compared to the glass tank.

The make and material of your tank depend entirely on the direction you choose for it, so be sure to consider this before choosing.

The Right Pricing

Since the all-in-one kits available for starter tanks like the 20 gallon tank is not as available for most 30 gallon tanks, the tank’s price is a factor that should not be overlooked.

One matter that seems to be often overlooked (even by long-time collectors such as myself) is the warranty factors. Some brands offer cheaper tanks that are not as durable. Other brands have pricier tanks, and sometimes it is because of the tank’s warranty. The warranty represents the brand’s faith in the product, and it also serves as a fallback for you in the long run.

When choosing the perfect 30 gallon tank for you, remember these important factors beforehand! Knowing is already half the battle, and learning about these factors will help you greatly with a better fish tank collecting experience.

Frequently Asked Questions


How many fish can I put in a 30 gallon tank?

It’s only possible to determine the amount by knowing each fish’s size. But there’s another way of going about this question. You simply follow the one-inch of fish per gallon guideline.

So if you have a 30-gallon salt water tank, it’s acceptable to have 30 inches of fish. I’d recommend sticking with a little under 30 inches for comfort reasons. But generally, this guideline has proven effective at keeping aquariums safe and healthy.

What is the most suitable fish for a 30 gallon fish tank?

Any 30-gallon tank will be wide enough to fit a variety of fish. But If I had to recommend one, it’d be guppies who are remarkably small and skinny. For instance, you can easily fit about 10 to 12 in these aquariums.

Some other excellent choices include rainbowfish, tetras, and angelfish. I’ve had great experiences with all of them during my time owning aquariums.

How big is a 30 gallon fish tank?

You might be surprised that a 30-gallon (about 113 in litres) capacity doesn’t mean it’s a 30-inch fish tank.

Instead, 30-gallon fish tanks will differ in their measurements significantly. So it’s vital to make a size comparison between available options before making a final decision. It’s the only one to ensure your new tank can fit into the intended space.

In most cases, these tanks have measurements close to 36″ L x 16″ H x 16″ W. It’s the acceptable average and what most manufacturers use when crafting them. Therefore, it’s a good starting point for any would-be owner.

What are the most trusted 30 gallon fish tank brands?

There are less than a dozen trusted brands for 30-gallon aquariums, most of which I have featured in the list of top ones above. These are:

  • Seaclear
  • Aquaculture
  • Coralife
  • Marineland
  • Fluval
  • Marina
  • Aqueon

How to set-up and use the 30 gallon fish tank?

The first step in setting up a 30 gallon tank is to clean the tank itself thoroughly. After doing so, then you should plan the placement. Although the 30 gallon fish tank is only a midsized tank, planning its placement is not as easy as the placement planning done for the nano entry tanks, which only takes a few minutes at the very least.

With the 30 gallon tank’s size, and the weight it would carry, the placement needs to be solid and sturdy. Prepping the water is next, which is done by placing the water you are to use in a separate tank and letting it sit to get rid of unwanted chemicals. As you wait for the water, plan the design and the route you are to take with the tank and decorate it. After sitting for a couple of days, fill the tank with half your water as your prime and test out your other equipment.

After this, fill the tank with all the water and let it sit for a couple of days. This process might be sped up with live plants and some biological filter media. Only after completing this process will you be able to stock the tank with the fish of your own choosing.

How to take care of and clean the 30 gallon fish tank?

One great aspect with the 30 gallon tank is that its size is big enough to prevent visible waste build-up from inside the tank. With the smaller tanks, a tight cleaning schedule is needed in order to maintain the water integrity, as the space is small and is easily overtaken by the nitrogen cycle.

The 30 gallon tank is perfect for beginners since it is easier to clean and therefore does not require as rigid a schedule. This is assured by the filtration that occurs from inside the tank namely the biological, mechanical, and chemical filtration.

With biological filtration, the biological media in your filter, as well as the whole tank space, is utilized by the friendly bacteria in order to build an active colony. These non-harmful bacteria aid the tank owner in cleaning as it breaks down the debris left by the surplus of food, excrement, etc.

Mechanical filtration, meanwhile, captures the bigger debris in the media and aids the owner by making the clean-up easier. Chemical filtration occurs when tank chemicals are added to the tank or by way of filter media, and it improves water quality by breaking down the unwanted toxins in the tank water.

Basically, aside from the owner physically removing floaters from time to time and cleaning the filters, the cleaning is done from the inside.

Where to buy?

For all your aquarium-related equipment, you can always visit your local pet store. You can also check with Walmart, PetSmart, PetCo or even HomeDepot. But if you want to make your life easier, just get yours at Amazon!


You are now venturing into the realm of the aquarium enthusiast, and not just a curious dabbler. It is therefore highly recommended to choose nothing but the best 30 gallon fish tank, especially if this is your first time getting one. Once you have your marine life set up, you won’t regret a single bit of it.
