API Phos-Zorb Aquarium Filtration Media

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 API PHOS-ZORB, a phosphate-removing filter media. API PHOS-ZORB comes in a specialized convenient pouch that eliminates cloudy water caused by phosphate and silicate. API 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.

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 test indicated the presence of phosphate or silicate.
