Phosphate levels exceeding 0.03 ppm will negatively affect coral growth as well as negatively influence the health of your fish. In addition, high phosphate levels enhance the growth of annoying algae and cyanobacteria. Most of current phosphate reducing products are based on granular ferric hydroxide and leak iron ions into your tank, which is enhancing algae growth and inhibiting coral growth and have a tendency to start clumping together, thus reducing its effectiveness.
Almost every other iron-based GFO is releasing iron ions into the water up to 10 times more than nbsp, natural seawater levels. This is tested and confirmed at the University of Wageningen, Holland. The tests were done with a inductively coupled plasma mass spectrometer.
Reef Interests PO4X4 Phosphate Remover is a unique, chemically engineered, polymer-based mini pellets. In other words, there is hardly any leaking of Iron ions, the pellets do not clump together, and can be readily used in fluidized filters. They have a high surface area and can absorb approximately 4 times more phosphate than most other phosphate removing products. 250 ml will remove 3 ppm of phosphate and silicate from roughly 8.000 liter of fresh water or 4.000 liter of marine water. Do not overdose! Rapid changes in phosphate can negatively affect your animals. Use small amounts of PO4X4 to gradually lower the phosphate levels in your aquarium.
PO4X4 is now available in 250ml and 500ml. PO4X4 works in perfect harmony with our NP Reducing BioPellets, Biopellets XL, or All-In-One Biopellets. However, All-In-One can replace PO4x4 once Po4 and No3 levels are both available for nitrifying bacteria to consume available nitrate.
Why does po4x4 remove 4 times more phosphates then normal GFO?
The Reef Interest PO4X4 consist of a polymer that is bound to pure FeOH2. Both the polymer, as well as the Iron molecules, are able to bind PO4. By combining these, we increased the binding efficiency. In addition normal GFOs consist of a mixture of iron hydroxide as well as iron oxide, while PO4X4 contains only Iron hydroxide. This means that PO4X4 with its higher content of Iron hydroxide, the form that binds phosphates, can bind much more PO4 then your average GFOs can.
