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.
