Frequently Asked Questions

How Important Are Aquarium Filters?

Fish tank filters are crucial—necessary—in any aquarium. An extremely important system that keeps the aquatic life in your tank healthy and bright is formed by aquarium filters and fish tank heaters. It’s up to you to decide which fish tank filter works best for you. Even though different filters function differently, they all serve the same fundamental function, which is to remove foreign objects and dirt from the water that would otherwise contaminate it.


Why Does a Tank Need a Filter?

The filter serves as the tank’s “heart” by ensuring that the water is always moving and preventing stagnation. In stagnant water, ammonia can accumulate and cause damage to your plants, fish, and shrimp. The tank can only hold a certain amount of oxygen due to the absence of water flow. You will need to perform frequent water changes and watch how many creatures you maintain in the tank if you want to have a tiny tank without a filter or air stone. The circulation of gases and nutrients throughout the tank, which gives your aquarium residents the necessities for a healthy life, depends on moving water. The water column will be kept clean and clear with the aid of a correctly functioning filter, giving you the clearest possible picture of your tank.


Different Types of Aquarium Filters

Canister Filters

These are some of the best filters in the market today. Canister filters function by suctioning out the water from the tank, and pumping them through the canister which is divided into various chambers where they undergo mechanical, biological, and chemical filtration before being pumped back into the water. Canister filters are ideal for people who have little time for aquarium maintenance as they would only need to be maintained once every quarter or more while keeping the tank water purified. Because the canister is situated outside of the fish tank, they are very easy to clean and do not make a mess. However, it comes with a high price. Their suction power is also generally strong which would not be great for small aquariums or ones where you would keep small, weak aquatic life.

Diatom Filters


These filters would give you one of the best filtrations compared to any other filter. Diatom filters use microscopic-sized earth particles are their filter media which do an excellent job at filtering out even the most minute of waste matter. Your fish will be swimming in the cleanest water they have ever been in. Just like the Canister Filter, these filters also come with a high price. Also, they require special maintenance and handling. The diatom media is so minute that if you accidentally breathe it in, it can affect your lungs. So they are more suitable for more experienced breeders with special fish that require great care.



These filters are very common especially if you buy your starter aquarium as a set. E filter consists of a raised base and gravel is layered on top acting as the filter media. Water is sucked through the gravel which traps waste matter, providing mechanical as well as biological filtration. Though it has received its share of bad press, it does function fairly well as a starter kit. The gravel needs to be vacuumed periodically to prevent it from getting clogged and diseased from decaying waste. It also does not have too strong suction, so is good for a small tank and weakfish.


Corner Filters

These are probably the cheapest filters you can find. I do not fancy these filters for some reason. Firstly, the filter media, usually a sponge, sits in a box that is also soaked in the aquarium water which is not hygienic. Secondly, cleaning the media will be messy, which involves removing the whole filter from inside the tank and taking out the filter media. This also involves placing your hands inside the water which will not be good for the fish. If this is what you can afford then it’s better than nothing but try to move up to one of the other filters soon.
