Do filters clean fish tanks?

The short and definitive answer is yes! A filter basically cleans the water of debris, removes the toxic buildup of ammonia and nitrates, and aerates the water so your fish can breathe. Which, unless you want an aquarium full of dead fish (or one filled with plastic fish), is a very good thing, indeed.

Can you keep fish without a filter?

Can a fish tank have too much filtration?
