Phosphate-E Brightwell Aquatics

Brightwell Aquatics Phosphate-E is a highly effective liquid phosphate remover designed to quickly reduce elevated phosphate levels in both freshwater and marine aquariums. Its lanthanum-based formula binds dissolved phosphate into insoluble particles that can then be removed by mechanical filtration or a protein skimmer. Key benefits: Rapidly lowers phosphate (PO₄) levels. Helps reduce nuisance algae and cyanobacteria. Promotes healthier coral growth and improved coloration by maintaining low nutrient levels. Suitable for reef and fish-only marine aquariums, as well as freshwater systems. Highly concentrated, so only small doses are needed. Directions: Dose slowly into a filter sock (5–10 micron is ideal), overflow, or skimmer intake where the precipitate can be captured. Test phosphate regularly with a reliable test kit (such as a Hanna ULR Phosphorus Checker) and avoid lowering phosphate too quickly. For reef aquariums, many hobbyists aim for 0.03–0.10 ppm PO₄, depending on the livestock. Important: Never pour large doses directly into the display tank. Remove or clean mechanical filtration after dosing to export the bound phosphate. If phosphate is very high, reduce it gradually over several days to avoid stressing corals.
