The Aqua Medic Sulphur Nitratereductor 400 combines both sulphur and nitrate reactors to remove nitrate and also neutralise the sulphuric acid produced.
This unit contains a circulation pump which aids the flow of water through the media.
The water is forced through the nitrate destroying sulphur media which creates a by-product of sulphuric acid. This is then pushed through the Hydrocarbonate media which removes the acid and restores the balance to the water.
The Sulphur Nitratereductor is recommended for aquariums up to 400 l.
