Why Does a Small Tank Need an Aquarium Filter?

Every living being, despite its size, creates waste. The same goes for fish too. Any tank size won’t perform well with a high deposition of waste rich in ammonia and nitrate.

So, if you are consistently struggling to find the significance of a water filter in a small tank, we got you.

Biological Filtration

The most important reason for an aquarium filter is biological filtration. The filter actively eliminates the waste accumulated in the tank over time. The more feeding a fish has, the more waste they’d create in the tank.

Not cleaning this results in higher levels of ammonia and nitrate in the water tank. This makes the water highly toxic for the fish to live in. Lack of biological filtration even leads to infections. Therefore, the main objective of a filter is to minimize the toxicity of the waste generated.

Mechanical Filtration

Another important reason why small tanks need a filter is to remove particles from them. It can include smaller grains of the substrate, dead plant leaves, and so much more. These free-floating elements can harm the fish or obstruct their path while swimming.

The filters mechanically remove them from the tank to enhance the tank’s cleanliness. Most of these filters have a sponge-like middle layer that filters out these elements.

Chemical Filtration

Last but the most important importance of a filter is chemical filtration. The filters detect any rise in a chemical imbalance in the water and filter out the same toxic elements. The activated carbon filters are responsible for taking care of that aspect.

The filter keeps the water flowing around so that the chemicals don’t stay stagnant in one spot. This promotes enhanced cleanliness without compromise.

FAQs

Will Changing my Filter Media Make My Tank Quieter?

Several factors contribute to the noise from the filter. So, the only way you can make the tank quieter is by identifying the problem. Once you know what’s causing it, you can fix the issue to reduce the noise output. Typically, it can be due to improper placement, accumulated dirt in the filter, and so much more. So, find the cause first and then fix it accordingly. Just changing the filter media is not the solution.

Can I Make an Air Pump Quieter for My Sponge Filter?

Sponge filters are a lot quieter than the staple ones. In addition, since the sponge is a lot porous, it actively absorbs the excess noise, helping reduce the noise created, especially with the bubbles. However, you need to choose a dense and high-quality sponge with air pumps to achieve similar results.
