The types and sizes of filtration the aquarium is equipped with greatly influences the number of fish that can be kept. Using several filtration methods on the same aquarium that remove different forms of waste can increase the capacity of a fish tank, but one needs to remember that during long power outages, too many fish can be disastrous.
