C-1300 Dophin Canister Filter

Its the best external filter .Sufficient for up to 100 gallon tank ..Makes my aquarium crystal clear ..Note : external filter is just a motor + crtridges. So everything depends on what kind of bio media u are using .I use -ZeoliteBioceraActivated charcoalCeramicUltra Fine sponge filterIf all of the above is usedThan no need 2 worry about your tank . It will remain healthy . Cleaning : needs only once in 2/3 months..

It's price is ok but this product work ok ok water clien is not satisfied my tank is only 3 feet...

Good quality. All filter media supplied. Runs quiet and efficient.EDIT: Running for 6 years... Very quiet and reliable.. superb build quality.

Best filter superb output first it will make some noise but when it sets it will run as smooth as butter
