NF Series - Sulfur Nitrate Filter

The Deltec Sulphur Nitrate Filter is a biological filter in which special bacteria (thiobacillus denitrificans) remove nitrate from the aquaria water. The time span for proper functioning can be rather long. After the running-in period, maintenance (apart form checking the exact water flow) is simple.

The water coming out of the Deltec Sulphur Nitrate Filter will have a low pH value and should be lead through a container with ROWAlith C or similar. For better performance the filter is fitted with a circulation pump.
