The dual action Aqua Internal 400 filter cartridges have been designed to be used specifically with the Aqua Internal400 filter. The dual action filter cartridge consists of the 3 forms of filtration: mechanical, biological and chemical. The fully open structure filter foam provides optimal mechanical filtration and creates a vast bacterial growth area. The chemical filtration section of the cartridge includes Norit ® active carbon to remove organic contamination, chemicals and dyes from the water. Each media pack contains 1 cartridge.
