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 FOR USE:
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.
