The construction of the Aqua Medic Sulphur Nitratereductor 400, available from Swell UK, is technically almost identical to the Nitratreductor 400.
It contains a circulation pump that circulates the water through the sulphur beads and the Hydrocarbonate.
Otherwise, than the known Nitratereductor, the Sulphur Nitratereductor uses special bacteria that use sulphur as energy source to remove nitrate.
As a by product, sulphuric acid is produced, that is neutralised by the Hydrocarbonate in the filter.
The Sulphur Nitratereductor is recommended for aquariums up to 400 l.
