Nano-Tech Phosphree
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 particules into the main tank.
In contrast, Phosphree keeps your tank water clear and sparkling.
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.
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.
Comes in two sizes:
500ml / 17 fl oz
500 ml (17 fl oz) will remove 3 ppm of phosphate from a 2000 liters (528 gallons) marine/reef aquarium.
250ml / 8.5 fl oz
250 ml (8.5 fl oz) will remove 3 ppm of phosphate from a 1000 liters (264 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.
※ Tank A: 100L of seawater with 60ml of Iron-Based Absorbent
※ Tank B: 100L of seawater with 60ml of Aluminum-Based Absorbent
※ Tank C: 100L of seawater with 60ml of Nano-Tech Phosphree
※ Photometer used to test for phosphate: Hanna HI97713 Phosphate Low-Range Portable Photometer
Step 1: Preparation of 100L of seawater with 1.0ppm phosphate content.
The tests cannot be conducted in an actual aquarium with livestock because phosphate is constantly generated by the animals. Hence we prepare the testing environment using Tricalcium phosphate.
We add 326.6mg of Tricalcium phosphate into 100L of seawater to bring the phosphate level to 1.0ppm (±0.03)
