The Cascade® 700 Canister Filter can handle aquariums up to 65 gallons efficiently providing up to 185 gph of flow. These filters allow you to combine the benefits of several types of media delivering powerful mechanical, chemical & biological filtration for crystal clear water in fresh or marine environments.
