Maxspect 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.
Granular ferric oxide or GFO, not only clouds the water when used, but also leak small black colored particles into the main tank. In contrast, Nano-Tech Phosphree keeps your tank water clear and sparkling.
In addition, 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.
Nano-Tech 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.
How to use
Place Maxspect Nano-Tech Phosphree in a textile filter bag for media.
Do not fill the mesh bag too full, leave 25-30% room for the resin to expand as it'll grow in size after it's been place in water.
For maximum absorption efficiency, place the resin mesh bag in the sump with medium to high flow.
Keep the resin moist for maximum shelf life - after opening the seal of the can, periodically spray a little distilled RO water into the can.
250 ml (8,5 fl oz) will remove 3 ppm of phosphate from 1000 liters (264 gallons) marine/reef aquarium.
