Chemical filtration is the simplest way to remove potentially dangerous pollutants from fresh and saltwater systems. There is a variety of chemical filter media available. Most chemical media remove specific pollutants from the water column while others are combined to create multi-functional chemical filter media that simplify removal of multiple pollutants.

Phosphate Removers
This form of chemical filter media is highly porous and super absorbent. It effectively binds large concentrations of phosphate, dissolved organic compounds, heavy metals, and other pollutants. High phosphate levels reduce water clarity and feed undesirable organisms, such as nuisance algae. In saltwater aquariums, phosphate can precipitate dissolved calcium and magnesium, vital for healthy coral growth. Many phosphate removers are formulated for long-lasting control and have high saturation points to help prevent absorbed pollutants from leaching back into your aquarium's water. Though many forms of phosphate removers are available, most reef hobbyists prefer ferric oxide hydroxide-based formulas.
