How Do Aquarium Filters Work?

An aquarium filter is essential to any fish tank setup. It helps keep your fish tank clean -- and helps keep your tropical fish healthy! But how does it work? Learn more about how this tropical aquarium essential works and why it’s such an important part of a healthy fish tank.

How Aquarium Filters Work:

  1. Biological Filtration - Biological filtration involves the bacteria and other microorganisms in your tank that convert fish waste into less toxic substances. As your fish excrete waste or leave food to decompose on the bottom of the tank, ammonia is produced. This ammonia is toxic to your fish. Your biological filter will convert ammonia into nitrite and nitrite into nitrate. This is why it’s so important to “cycle” your tank when it’s new!

  2. Mechanical Filtration - Mechanical filtration is the part of the filter that strains out free-floating particles like waste and food. Your mechanical filtration will need to be cleaned frequently so that it doesn’t become clogged with debris.

  3. Chemical Filtration - Last, but not least, chemical filtration in the form of carbon helps extract toxins from your fish tank water. Activated carbon is used to help keep the levels in your fish tank healthy.

Of course, even the best filter doesn’t substitute regular water changes! Both regular filter maintenance and water changes are essential to maintaining your fish tank water quality.
