Aqua-Tech Co Phos4 Molecular Phosphate Resin 5 lb Bucket
The Phosphorus atom is one of living matter's basic building blocks. It is present in every living creature and in every reef aquarium's water. Unfortunately, it is often present in excess in reef aquaria, and that excess has the potential to cause at least two substantial problems for reefkeepers.
Flake fish food is typically about 1% phosphorus (3% phosphate equivalent) by weight (and many products have such phosphorus data on their labels). Consequently, if five grams of flake food is added to a 100-gallon aquarium, there is the potential for the inorganic orthophosphate level to be raised by 0.4 ppm in that SINGLE FEEDING!
Many reef aquarists may not recognize that they have a phosphate problem, only that they have an algae problem. The algae may be consuming the orthophosphate as fast as it enters the water, thereby masking the issue. In this case phosphates test kits many times will read as zero or very close of zero and consequently, many reef aquarists may not recognize that they have a phosphate problem, only that they have an algae problem.
The presence of phosphate in the water also decreases calcification in corals and this inhibition of calcification takes place at concentrations frequently attained in reef aquaria, and may begin at levels below those detectable by hobby test kits.
For example, one research group found that long-term enrichment of phosphate (0.19 ppm; maintained for three hours per day) on a natural patch reef on the Great Barrier Reef inhibited overall coral calcification by 43%.
