API Phos-Zorb 55gal
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.
