Ammonia stress could progress into ammonia poisoning and could be deadly if this condition is allowed to continue.
  • Filters are fish-friendly. In point of fact, if you do not invest in a topnotch filter, you will need to clean your small aquarium on a periodic mode and that would mean the need to scoop out your pet fish and set them aside for you to possibly and easily give the fish tank a thorough scrub.

A good filter works to get rid of excess food and waste that your pet fish do not consume at once- this diminishes the hazard of health problems and fish death.

Frequently Asked Questions

I also must point out that some types will last longer than others. For instance, an external filter for small aquarium tanks has a much better chance of reaching its maximum lifespan. It doesn’t experience the same wear and tears as an internal filter.

What are the most trusted small aquarium filter brands?

How to set up?

Fundamentally, the mechanism of setting up a filtration system for a small aquarium starts by means of ensuring that your filter is properly assembled prior to the installation process.

Nearly all manufacturers nowadays would send the filter to the consumer with some components unassembled. This is commonly to save more space during shipment and for practical reasons. Moreover, you will need to look for all the components in the shipped package and all you need to do is to put the parts together.

Whatever brand or manufacturer you choose to purchase, they generally provide some instructions on how to put the whole product together. It is indispensable to strictly adhere to the procedures in the manual so you can easily and accordingly assemble the filter in a snap.

Please be reminded that most filters may require being assembled together with a few parts and it is all set to function. Anyhow, here are some guides when installing the filter for your small aquarium:

  • At the time you’ve made all the connections to the filter as a component of the setup process, it is high time to set the filter up. It is crucial to position the filter into the small aquarium under gravel if you are using the under gravel type of filter. Here, be sure that it is well suited in place prior to filling the aquarium with water.
  • The lift tubes must be properly fitted as this could greatly assist the filter in executing its function accordingly. Then, continue by linking the powerhead and pump airlines to the suitable lift tubes prior to turning it on.

It is feasible for you to acquire the external water filters as these are typically more plain sailing to put together and can be mounted on the water tank for them to start functioning.

These often come with an external power cable that links it to the primary power for filtration to begin. It is valuable to make certain that the power cable does not reach the water to avoid unfortunate incidents from emerging.

In substance, it is vital that you don’t get to switch on the filter except that the aquarium is filled with water in both instances.

How to care & clean?

The main purpose when cleaning an aquarium filter is to remove dirt particles that pile up as well as the disintegrating organic substance inside the fish tank. However, it is also essential to be extra cautious about removing otherwise you’ll end up exterminating a generous amount of good bacteria as well.

As much as possible, it is highly suggested to avoid the use of very hot water when tidying up the filter and see to it to refrain from using chemical-based cleaning agents- either of these could exterminate your biological filtration system.

Here are some guides when cleaning, caring for and maintaining your filter:

  1. See to it that there is water in the pump chamber. Otherwise, the filter would end up pulling in air.
  2. Pay attention to the amount of water inside the fish tank. Take note that nearly all filters especially require the water level to be roughly an inch from the filter’s lip.
  3. Make it a point that the air stones or bubble walls aren’t directly positioned below the intake tube. The reason for this is that if bubbles rise up to the primary tube, this will bring about irking sound and worse it might halt the filter from functioning properly.
  4. It is important to utilize gravel in the fish tank rather than fine sand. This is because sand could bring about some issues with the impeller since sand tends to get between the energizer and the magnetic impeller, averting it from turning.

On the other hand, if you already have sand in your fish tank, consider using a mesh net which you could purchase at the local aquarium or fish store or online and then put in on the strainer. You can also use panty hose as an alternative.

The filter would pull out the dirt particles; nevertheless, it would not pull up the sand.

Please be guided that if you have multiple filtration systems set up in your small aquarium, consider alternating your cleaning schedule for you to execute all of them in the same week possibly. For this, you may come up with a periodic cleaning schedule and see to it to strictly adhere to this schedule as closely as you can.
