RENA Smart Filter 20
The RENA SmartFilter is revolutionizing the power filter category by bringing the superior filtration of a canister filter to the back of the aquarium, in this awesome hang-on filter series.
The RENA SmartFilter offers unparalleled functionality, including unique pressurized filtration so water flows through – not over – the filter cartridge. It also offers easy water flow adjustment knobs to control water flow.
The 4-sided filter cartridge contains Bio Chem Zorb™, the most advanced filtration resin available, to deliver crystal clear water. The SmartFilter also features the most convenient cartridge replacement system, with a universal, one-size-fits-all cartridge. The revolutionary cartridge caddy is easy to access and features a drip-reduction cup. It can also be combined with the RENA SmartHeater to offer an integrated filtration and heating unit for less aquarium clutter. A truly innovative design from RENA.
