Aquarium Power Filters
Power filters are the type of filter most people think of when they think of an aquarium filter. This type of filter is often referred to as a hang on aquarium filter, because it hangs on the back of the aquarium between the aquarium and the wall. This type of filter is very simple to maintain, is quiet, and efficient to use. Each manufacturer has strengths and weaknesses to their filter, with some like the Aquaclear filters being well known for superior mechanical filtration and others such as the Marineland Bio-Wheel type filters being well known for its great biological filtration.
