API Phos-Zorb Size 6 - Filter Media Removes Phosphate

PHOS-ZORB filtration media is scientifically proven to remove phosphate and silicate. 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.


  • Eliminates cloudy water
  • Scientifically proven to remove phosphate and silicate

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.
