There’s no question about it, filtration is a necessity with having fish. You might be faced with a big dilemma where you’re wondering what the best filter freshwater aquarium would be. To start with finding one, you do have to understand that your tank is basically a closed system. Because of that, any uneaten food and even fish waste can easily accumulate in your tank and make your fish environment toxic and poisonous. Even if you clean your tank every day, it’s still best when you get a great filtration system for your tank to ensure that everything is perfectly balanced for your fish.

The best filter freshwater aquariums come in three different types. You have the chemical filter, the biological filter and the mechanical filter. If you want to ensure that your fish are healthy, you have to invest in a whole filtration system that does all three things. Each type of filter takes care of some kind of waste or dirt in your tank to keep the tank a great environment for your fish to live in. With the best filtration system, you also don’t have to go way out of your way in the maintenance process of your tank.

A mechanical filtration will work on fish excrement and uneaten food. For the best filter freshwater aquarium under this type, you can a choice between coarse to fine grades of filters. With the use of foam or even filter fibers, you can make sure that even the small particles of debris in your tank are taken care of.

Whatever debris your mechanical filter didn’t get, it’s going to be passed through the chemical filter where it’s broken down and cleaned out from your tank. Bear in mind that ion exchange resins work on a particular type of ion. For the most part, you can make do without ion exchange resins in your chemical filtration.

Lastly, you have the biological filtration. For this particular filter, you have colonies of helpful bacteria working on the water and your tank. They do their part with breaking down any waste products from your fish and any waste products from overfeeding. When you have tank water that’s left untreated by filtration, you’ll easily end up with water that’s toxic for your fish. Bacteria in this filter will take care of things like ammonia and nitrite. Any kind of filter you get for your tank will do a great job, but the best filter freshwater aquarium will be something that combines the three types available.
