Canister filters are the best choice for serious hobbyists. They require less frequent cleaning than hang on type filters and work much more efficiently.
Eheim Classic 2213, 2215 & 2217 canister filters have the longest most reliable track record in the trade. A pump/motor unit that seems to run forever with a minimum of service.
Eheim patented the principle of plumbing the water into the bottom of the canister. This design guarantees that no water can bypass the filter media, while eliminating the need for space wasting media baskets. This allows the canister to be 100% full of media top to bottom, side to side!
Proven technology, balanced performance, and high efficiency mark classic series filters as the bellwether in aquarium filtration. One chamber design allows for the greatest flex in setting up for mechanical, biological, chemical and adsorptive filtration.
Flow rates have been precisely calculated to provide the exact balance needed between mechanical and biological long-term filtration, water circulation and oxygen enrichment, resulting in optimum conditions for successful aquarium keeping, with 3-6 month maintenance intervals. Also ideal for specific purpose filtration such as Chemical /Adsorptive (carbon).
