Phos•Correx is a technologically advanced, premium quality, maximum strength phosphate remover that immediately and safely begins to reduce the reactive phosphate present in a saltwater aquarium. It may be used on an ongoing basis to keep phosphate levels under control. Keeping a very low to immeasurable phosphate level is one way to keep a cleaner, more pristine aquarium.
It is not recommended that you add more than the dosage given in the directions, per day, so that you don’t irritate sensitive corals by reducing the phosphate level too rapidly. Because Phos•Correx precipitates the reactive phosphate by binding it, it will tend to cause cloudiness in the aquarium, which should be removed by mechanical filtration, and protein skimming and is temporary.
