As well as the usual Biomax media for your aquarium filter, you may wish to add a U1/U2/U3/U4 Clean & Clear Cartridge from Fluval.

These cartridges have been packed with high-performance resins which have been proven to reduce nitrate and phosphate within the aquarium resulting in a cleaner, clearer and more healthy environment for your fish. Simply insert the cartridge into your filter alongside the already present filter media and the results will speak for themselves.

Suitable for the U1, U2, U3 and U4 Fluval internal fish tank filters.

Comes as a pack of 2.
