Multi-Stage filtration
Fluval's Multi-Stage filtration system utilizes the entire canister volume for radically increased water flow efficiency. Its mechanical stage features vertical twin foam pre-filters, to increase flow and reduce maintenance. The chemical and biological stages are housed in independent modules. This means you can change filter media independently and ensure a constant level of all important nitrifying bacteria.
