Aquarium Filters are used to process waste and impurities to maintain pristine water quality and keep your tank inhabitants healthy. There are numerous types of fish tank filters, each a little different and used in different applications. A quick lesson in aquarium filters will teach you the basics and help you make a more educated purchase.

Some of the most popular filters include the Canister Filters and Hang on the Tank Power Filters. These filters are suitable for freshwater, saltwater and reptile/amphibian set ups.

Internal filters can be very useful in quarantine aquariums, freshwater tanks, temporary holding tanks and reptile/amphibian setups.

Wet/dry filters rapidly breakdown ammonia and nitrite making these filters extremely efficient and an outstanding choice for freshwater and saltwater aquariums.

Specialized reactors such as the phosphate / GFO reactors and biopellet reactors (marine aquariums only) can be very helpful in lowering nitrate and phosphate levels.
