Fluval ribbed hosing is beneficial for a number of reasons! It’s quick and easy to install, does not kink or collapse over time, is not influenced by temperature, maintains a wide, constant water flow area over the aquarium rim, and its aesthetics are not compromised over time. Most importantly, Fluval ribbed hosing provides superior clog resistance to help prevent loss of flow rate: third-party testing has shown that after only 4 months of operation, a 36% decrease in flow rate was observed with standard PVC hosing, whereas only a 1% reduction in flow rate was observed with Fluval ribbed hosing after 7 years of operation.

The water first passes through the foam pads as it moves to the bottom of the canister. It then rises to the top through the media trays and exits the canister.
