Phosphorous is often present in excess in reef aquaria, and that excess has the potential to cause at least two substantial problems for reef keepers. The first is that phosphate is often a limiting nutrient for algae growth, so when elevated it can permit excessive growth of undesirable algae. The second is that it can directly inhibit calcification by corals and coralline algae. Because most reef keepers don’t want either of these things to happen, they strive to keep phosphorus levels under control. Fortunately, there are several effective ways to keep phosphorus concentrations at acceptable levels and using a phosphate reactor with high quality phosphate removing media is one option.

Many commercial phosphate binders are used in reef aquaria. Many of these are inorganic solids that bind phosphate onto their surfaces. One common type is aluminum oxide (such as Seachem’s PhosGuard™ and Kent’s Phosphate Sponge™). Another common type is iron oxide hydroxide (such as ROWA®phos, PhosBan®and Salifert Phosphate Killer™). These materials primarily bind inorganic orthophosphate, but they may bind some organic materials as well.
