Aqua Medic Nitrate Reductor

SN400 Nitrate reductor using sulphur beads as food for the bacteria, for use with seawater aquariums up to 400ltrs. 

A slow water flow through a filter medium produces a low oxygen (anaerobic) environment for the nitrate reducing nitrobacter bacteria. The lack of oxygen means that the bacteria then utilize the nitrates (NO3) in the water to source their oxygen in order to breath. The end result of this nitrate breakdown is nitrogen gas (N2) which is harmless. However, the bacteria also require a food source. 

The SN 400 uses sulphur beads as a surface for the bacteria to colonize and also provides the food source. 

The gradual consumption of the sulphur beads by the bacteria produces sulphuric acid as a waste product. 

This acid is converted into calcium carbonate by the hydrocarbonate layer in the reaction chamber, which also enriches the calcium level of the aquarium. 

A circulation pump inside the filter chamber moves the water throughout the media, eliminating any dead areas. 

Please read all instructions carefully when using this product and note the requirements concerning the operation and also water maintenance.
