API Phos Zorb
API PHOS-ZORB cartridge eliminates cloudy water and dirt caused by phosphates, and helps reduce the maintenance of your aquarium. PHOS-ZORB removes phosphate and silicate, which are common nutrients found in fresh and saltwater aquariums that contribute to water murkiness, and additionally removes compounds that inhibit aquatic plant growth.
DIRECTIONS:
Rinse pouch under tap water for several minutes to remove dust and activate PHOS-ZORB. Place pouch in path of water flow in the aquarium filter. Replace the pouch every 2 months or when testing indicates the presence of phophate or silicate.
