Go with the flow and keep your tank sparkling clean. Choose from our list of the best aquarium filters to ensure your tank is properly maintained.
Your aquarium is an enclosed environment, so the water gets dirty pretty easily. Not only are we talking about uneaten fish food and feces breaking down, but the chemical byproducts of those processes as well. If you don’t perform routine maintenance in your tank, toxins will accumulate, and it can become a deadly environment for your fish. Having a good aquarium filter in place is essential for maintaining high water quality and a safe, healthy environment for your tank inhabitants.
In this article, we’ll discuss the importance of having an adequate filtration system in your aquarium. You’ll also see our top picks for the best aquarium filters to consider for your tank.

Adequate filtration is essential to maintain high water quality in your tank for the benefit of your fish. There are a variety of different aquarium filter types out there, but it is largely a matter of preference which option you choose. Canister filters are a favorite of many aquarium hobbyists because they are large, efficient, and easy to customize.

The Importance of Aquarium Filtration
There are three types of aquarium filtration: mechanical, chemical, and biological. Mechanical filtration involves physically removing solid waste like uneaten fish food and feces from the tank. Chemical filtration tackles dissolved wastes and toxins while biological filtration simply involves cultivating a colony of beneficial bacteria in the tank to help maintain balance. A good aquarium filter will incorporate all three types of filtration, though there are several different models to choose from.
Here are some things to look for when shopping for an aquarium filter:
- Filter Type – The type of filter you choose is largely a matter of preference but consider the pros and cons of the different options before you decide.
- Size/Flow Rate – Aquarium filters are rated for tanks of different sizes according to their flow rate – it’s best to choose a larger filter than you need rather than a smaller one.
- Filter Media – The filter media is what provides the filtration benefits, so be sure to choose a filter that incorporates mechanical, chemical, and biological filter media.
- Maintenance – You’ll need to change your filter media once a month and clean the filter as well – look for a model that is easy to disassemble and reassemble after cleaning.
- Convenience – Some filters come with convenience features like self-priming pumps that save you from the hassle of having to siphon water.
No matter what type of aquarium filter you choose, it’s important to keep it properly maintained. Changing your filter media every few weeks and cleaning the filter once a month will keep it in working order. Do a quick check on your filtration system once a week to make sure things are still running and clean the parts a few at a time instead of doing it all at once. This way you avoid killing off too many of the beneficial bacteria living in your filter.
