PO4X4 Phosphate Remover 500ml

Phosphate levels exceeding 0.03 ppm will negatively affect coral growth and higher levels will also 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 to the water up to 10 times more than 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.

Our novel PO4X4 Phosphate Remover is a unique chemical engineered polymer based mini pellets that does not have these down sides. 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 very high surface area and can absorb approximately 4 times more phosphate then 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 availeble in 250ml and 500ml. PO4X4 works in perfect harmony with our NP Reducing BioPellets and ReefPearls.

Why does po4x4 remove for times more phosphates then normal GFO?


The PO4X4 consist of a polymer that is bound to very pure FeOH2. Both the polymer,as well as the Iron molecules, are able to bind PO4 and
by combining these we increased the binding efficiency. In addition,PO4X4 which contains only Iron hydroxide, normal GFOs consist of a mixture
of iron hydroxide as well as ironoxide and only the first form can bind phosphates. This means that PO4X4 with its higher content of Iron hydroxide
can bind much more PO4 then your average GFOs can. The PO4X4 can be regenerated up to 98% with our regeneration buffer. You can use NaOH
as well, but this will do the trick up to 60%. This means that after 5 cycles of regeneration the product has worn out, whereas our special regeneration
buffer (which does contain NaOH among others so be careful while handling it) can be use up to 20 times and probably more.
