What To Look For When Buying An Aquarium Sump


When picking the suitable size and kind of fish tank sump, it matters to take some points into account. The kind of filtration system is the most topnotch factor that you need to think through when it comes to the kind of fish tank you currently keep. More than that, also consider if your new fish tank will call for other temperature control tools or other filtration devices.

In reality, refugiums or aquarium sumps are slightly pricey nowadays; thus, rushing to get just any brand is not a smart move to make. Some of the aspects that must be pondered on when purchasing a sump for your fish tank may comprise of:

Size. The sump has to be large enough to conform to the size of your fish tank and the number of gallons it contains. Take in mind that a sump should be a minimum of 1/3 or ¼ the size of the actual fish tank.

Indeed, see to it that it is large enough to suit all of the elements that you plant on adding to it. Check the size of your tank first to ensure that you are getting the right size that won't congest the inside of the tank.

Sturdiness. A sump should be durable to withstand rugged use and ensure long-lasting service. In general, sumps made of superior quality acrylic or glass materials are the most suitable options to go.

It helps to go over some customer testimonials prior to making the final purchase so that you can be guaranteed that it comes with professionally-sealed seams and won't have leakage issues for you to worry about in the long run. Needless to say, a punctured sump will result to a slippery and drenched floor which is of course very undesirable and dangerous.

Good Combination. In the event that you opt for a large sump fish tank to serve as an effective filter and at the same time you prefer a roomy space for a refugium, then you may choose the one that comes with several huge chambers. Make sure that one of those chambers can be utilized for a refugium. This way, it won't be focused on a single purpose.

Sump Accessories. These are also very valuable components to mull over when purchasing a sump. It makes sense to carefully inspect if the sump comes with micro sponges, protein skimmer, filter media and micro socks. As you might already know, these are very practical and functional accessories that are quite useful if you hope to keep a clean and safe fish tank for your aquarium pets.

The appearance of the sump. Of course, it is preferable to opt for the one that is aesthetically appealing and can make your fish tank look impressive.

Flexibility or versatility. The designs of sumps normally come with several chambers and easy-to-adjust baffles that permit fish tank owners to work around the design so that they can fine tune it to different aquarium equipment.

Smooth sailing to set up. Not to mention, nobody wants to deal with tedious installation procedures, so you might as well choose a sump kit that won't give you a headache when putting it all together. Look for those with installation instructions or installation videos available. In so doing, you can have an easy guide on how to execute it on your own.

Noiseless operation. As much as possible, we don't prefer sumps that generate noise when running. Luckily, many modern options come with silent operation mode nowadays.

Other Important Factors to Consider


What is an aquarium sump? How does it work?

A sump refers to an additional tank or a separate aquarium that serves as a spot where you could add protein skimmers, filters, various fish tank cleaning devices as well as pumps without the need to actually have them inside the fish tank. In other words, it is an extra tank where you can place all the necessities so you can save an adequate amount of space in the actual fish tank.

What's more, this is a substantial piece of equipment that generally lies below the display tank. This is typically utilized in saltwater tanks mainly because a number of the most outstanding equipment available is intended to be put or stored in a sump.

Normally, this is positioned within the fish tank cabinet or sometimes it is drawn to a separate basement or fish room. This way, users can enjoy easier access; however, this is mostly done for larger-sized or commercial builds. When installing a sump, this is often times placed within the cabinet and there is a need to utilize an underwater return pump to shift the water back to the display tank.

A fish tank sump works by absorbing water from the main tank and transmitting this through a set of chambers, wherein each of these chambers serves its own purpose. A sump naturally includes micron filter bags that are designed to aid in eliminating detritus from the tank water; it could shelter a micro sponge to halt microbubbles from penetrating, it has the capability to make room for a protein skimmer to clear the water from any sort of dirt and it could also be adaptable with different filter media and the like.

To put it simply, a sump is similar to a multi-phase filter that lies outside the main tank. The water streams back into the fish tank after it has infiltrated the sump.

What are the different types of aquarium sumps?

Adding the right type of sump for the type of fish tank you are currently taking care of is definitely a must. While sumps are precisely designed for freshwater tanks, these could also be implemented in marine fish tanks.

  • Freshwater tank sump. This is basically a tank that accommodates all aquarium filtration media, filtration system, heater and water pumps that enable aquarium owners to maintain a mess-free display tank.
  • Marine tank sump. This enables for more spacious surface skimming of your saltwater aquarium. The water is siphoned from the sump into the fish tank and then this stream back into the sump to be strained and returned again- this is the process of a complete saltwater and sump system. In this manner, the level of water in the aquarium is kept consistent.

Why do you need an aquarium sump? (Benefits)

A sump is deemed as an essential device in that if you utilize more media for your fish tank, the more excellent your filtration system will be. Biological filtration with the aid of using a premium quality sump comes with a number of advantages and some of these are:

  • Can help enhance water volume to the entire filtration system
  • Provides ample spots where you can safely store your filtration media
  • Can be completely customized or set up according to your needs and media preference
  • There is no need to put your equipment in the main display of your aquarium so it's clutter-free. It's one great way to put things in place and be more organized.

As you know, if you keep your equipment in or on the main display of the tank, this seems to look cluttered and undesirable. However, try keeping this underneath the tank and below the stand and you'll see that this looks well-kept and mess-free.

In like manner, if you start keeping the equipment in the fish tank sump area, this will enable you to enjoy instant access to it. In this way, your aquarium pets won't be distracted and are less likely to feel stressed when you need to conduct the cleaning, water replacement and maintenance.

And, since fish tank also allows aquarium owners to improve the volume of water in their system, this would pave the way for more support and capability to protect more corals, marine fish, and other types of invertebrates without requiring bigger tanks or footprint.

Frequently Asked Questions


How big should a sump be for an aquarium?

Your aquarium's sump must be between ⅓ and ¼ of your tank's dimensions. This sizing will keep your tank from getting too congested when using a built-in sump. Most manufacturers make selecting a size manageable by advertising what tanks are compatible.

So if you're freaking out about optimal sump measurements, there's no need. Instead, stick with what the manufacturer recommends in the product description. From there, matching the sump with your tank's gallon capacity becomes a simple action.

Is a sump necessary for a reef tank?

A sump setup for reef tank aquariums isn't necessary. You can certainly ensure proper filtration without using sump filters. However, it's not a path I'd recommend for reef tank owners.

You'd be much better off relying on a high-quality sump for filtration. It's the easiest and most effective way to ensure your tank remains in good condition. So stick with an option like Eshopps' RS-75 Reef Sump to meet your filtration needs. It's been a godsend 55-gallon sump kit for my massive 55-gallon reef aquarium.

Are wet/dry sumps better for aquariums?

Wet/dry sumps, also known as trickle filters, offer better in certain tanks. For instance, I recommend using them in a reef, freshwater-only fish, or saltwater-only fish tank. These situations suit a wet/dry sump filtration aquarium setup.

If you use them correctly, the tank's water will be free of all unwanted contaminants. Your fish will be able to swim in its 10-gallon or larger tanks. It's certainly more effective than a sponge or power filter.

An excellent example of one would be Eshopps' AEO14005 Reef Sumps Rs-100. It's a perfect option for any tank over 75 gallons with impressive filtration results. Plus, it's well-known for being silent.

The only problem with wet/dry sumps is they're expensive, especially My Reef Creations Sumps. So anyone looking to use a saltwater or freshwater aquarium sump design must put aside a lot of money. It's why some people view using them as not worth using in smaller tanks.

What is the top-quality sump material?

Durability is a crucial aspect when choosing a high-quality sump. So picking a model from the top-tier available construction materials is vital. In most cases, acrylic is the most reliable option and less prone to structural damage.

Should a sump pit have gravel?

Yes, an inch of evenly spread gravel at the bottom of the pit can drastically improve the filtration system. However, there should be a stone paver set on top of the gravel to prevent the small pebbles from getting into your pump.

Is dry sump better than wet sump?

As far as aquarium sumps are concerned, there is no such thing as a purely dry sump. Such an option is only available for oil systems. In this case, dry ones are better than their wet counterparts due to their better holding capacity and superior horsepower output.

Do aquarium sumps work for both saltwater and freshwater?

Sumps have a substantial value in both marine and freshwater tanks, although these are largely employed in saltwater aquariums. The perks that sumps provide are definitely immense. These devices could actually offer a huge amount of surface space where you can practically store your aquarium equipment, this enables you to customize your preferred filtration system and it also makes it possible for you to establish a flexible space that could be utilized as a safe spot for freshwater plants, macro algae and fauna in marine tanks.

In general, the most crucial decisions you could ever come up with are picking your sump system and choosing the most appropriate fish tank sump for your needs and preferences and of course how to connect this with a top-quality sump pump that you could invest in.

Furthermore, sumps are utilized in saltwater fish tank hobby for a number of reasons. There are those who purposely implement sumps to aid in enhancing the total volume of tank water in order to make it a lot easier to sustain the recommended salinity levels and be able to reduce waste. On the other hand, other people utilize this device to shelter refugiums and other fish tank equipment necessary to operate a large-sized reef.

And, since there is no need to balance salinity levels in a freshwater tank or you won't need large filtration devices such as calcium reactors as well as protein skimmers, it is difficult to conceptualize that a freshwater system would require a sump. This would only be just a problem and ridiculously excessive expense for a freshwater tank.

How to install?

  • Create a plan for your sump. Such devices are generally customizable. It helps to conduct research to accordingly plan your sump prior to building it on your own. Keep in mind that you should include some adequate space to house different aquarium equipment like a heater and protein skimmer.
  • Put your sump together. When you already have a detailed plan on how to set up your sump, you may proceed to the assembly phase. When you put your sump together, you will need to fasten the panes into place to create baffles and edges for the refugium. Use acrylic baffles if you are utilizing acrylic sump and use glass baffles if you are utilizing glass sump.

In case you require drilling any of the glass panes to from baffles, you may execute this prior to fastening them in place mainly because it is a piece of cake to drill unfastened panes. See to it to allow the bonding agent to completely dry up and cure. As you know, some harmless fish tank bonding agents could have the tendency to release harmful chemicals when curing.

  • Setting up the equipment. It is significant to know that it is the return pump that serves as the primary piece of equipment that a sump especially requires for it to work more efficiently. Setting it up comprises of fastening it into the return plumbing- take note that this could differ hinged on the specific pattern of your sump and your tank accessories.

Sump commonly comes with aquarium equipment like automatic top-off systems, protein skimmers and heaters. It is a must to set up the equipment as directed by the manufacturer's instructions. It won't do any good if you submerse the equipment that is designed to work or run outside the water. Also, do not activate submersible equipment when it is not submersed. Please be guided that heaters and pumps could crack or get damaged easily if utilized improperly.

  • Final phase of installation. Prior to starting the sump, it is critical to first fill it with fish tank water and be sure to work on the finishing connections in the plumbing. Indeed, prior to activating the pumps, carefully label the level of water on the outside of the sump with plumbing with the aid of a permanent marker and mark it as “fill line.â€

At the time you start to turn on the return pump, you need to allow some time prior to the water starts to stream back into the sump. When you observe that the water starts to form a complete course, label the new low level of water and label it as “running line.†Bear in mind that it is not advised to fill the sump more than the amount of this line when the pump is in operation mode. If you do so, there is a greater likelihood that the sump will overflow once the pump malfunctions.
