A specialized, synthetic adsorption filtration media that selectively removes phosphate in fresh and saltwater aquariums, as well as silicate found in tap water. Phos-Zorb effectively removes phosphate and silicate and will not release them back into the water for long-lasting phosphate control. A clean aquarium environment free of excess phosphate means enhanced growth of corals in saltwater aquariums and superior plant growth in freshwater aquariums.

Phos-Zorb also helps prevent calcium precipitation caused by excess phosphate in reef aquariums to help promote the growth of reef-building corals. Effective for up to 8 weeks. Safe for all fish, invertebrates, and plants. Net weight 5.25 oz in mesh bag. Treats up to 55 gallons.

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.

General Information
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.
