Nano-Tech Phosphree is a polymer resin that is chemically stable and does not leak any metal ions into the water column unlike metal-based absorbents.

“Phosphree is specially designed to absorb phosphate at a much slower pace compared to other metal-based absorbents, giving time for corals to acclimate to the reduction of phosphate in the water column.”

Rapid reduction of phosphate in the water column could stress out corals, and in the worst-case scenario, may lead to Rapid Tissue Necrosis or RTN.

500 ml (17 fl oz) will remove 3 ppm of phosphate from a 2000 litres (528 gallons) marine/reef aquarium.

To establish a controlled environment for Phosphate Absorption Rate Test, we’ve prepared three tanks with 100L of seawater, all containing 1.0ppm (±0.03) of phosphate.
