Fluval G Nitrate Cartridge
The G3 cartridge will remove up to 13000mg of nitrate and the G6 will remove 23000mg of nitrate ion from freshwater aquariums. The cartridges will immediately start removing Nitrates and will have all excess nitrates removed within a couple of days. The nitrate is irreversibly trapped and bound and will not leach back into the aquarium water.
