Phosphate can enter the aquarium in fish waste, decaying organic matter and tap water.  High phosphate in the aquarium can cause water clarity issues.  Phosphate can be reduced with PHOS-ZORB, a phosphate-removing filter media.  PHOS-ZORB comes in a specialized convenient pouch that eliminates cloudy water caused by phosphate and silicate.  PHOS-ZORB removes these common nutrients and enhances the growth of hard and soft corals in saltwater. PHOS-ZORB also removes compounds that inhibit plant growth in freshwater aquariums.

When to use: When testing indicates the presence of phosphate (greater than 0 ppm / mg/L) or silicate (greater than 0.5 ppm / mg/L).

Treats: 1 large pouch treats up to 55 U.S. gallons of aquarium water Directions: Rinse pouch under tap water for several minutes to remove dust and activate the PHOS-ZORB.  The activation process will temporarily generate some heat.  Place pouch in path of water flow in the aquarium filter.  Replace pouch every 2 months or when testing indicates the presence of phosphate or silicate.
