Deltec Sulphur beads – 500g
Deltec Sulfur media is made from the purest grade of sulfur for use in nitrate reactions. Sulfur is the food source for bacteria that eliminates nitrates by converting them into nitrogen gas. They have to be replaced from time to time as they are slowly consumed by the bacteria.
Caution:Use in sulfur nitrate reactors having a low water flow rate. The water leaving the nitrate reactor has a low pH and can be dripped over calcium media to raise the pH before entering the aquarium.
