Brightwell Aquatics Phosphat-E - 2 Litre Brightwell Aquatics Phosphat-E - 2 Litre is a larger-format liquid phosphate remover for marine fish and reef aquariums that need routine phosphate control. It helps eliminate reactive phosphate and supports ongoing nutrient management in larger or heavily stocked saltwater systems. Brightwell Phosphat-E 2 Litre for Larger Reef Phosphate Reduction The 2 Litre size is useful for larger displays, service use, fish rooms, and aquariums where phosphate reduction is part of regular maintenance. Phosphat-E works by converting reactive phosphate into an inert particulate that can be exported through mechanical filtration and protein skimming. Phosphat-E Large-System Nutrient Control Features Liquid phosphate remover for marine fish-only and reef aquariums. Starts eliminating reactive phosphate immediately after dosing. Helps remove phosphate when dissolved organic material is abundant. Can be used for ongoing phosphate control in heavily stocked marine aquariums. Each 1 ml eliminates 1 ppm phosphate in 4 US gallons of water. Concentrated format is practical for larger aquariums and repeated use. Brightwell Phosphat-E 2 Litre Filtration and Testing Details Size: 2 Litre bottle. Use: Marine fish and reef aquariums. Product type: Liquid reactive phosphate remover. 2 Litre treats up to 8,000 US gallons at the overview strength rate. Temporary cloudiness can occur after dosing and should dissipate as particulate is removed. Mechanical filtration and protein skimming improve removal of the bound phosphate compound. Ingredients: Purified water and proprietary phosphate removers. Phosphat-E Dosing Directions for Larger Marine Aquariums Measure phosphate before dosing and make adjustments gradually. Add Phosphat-E near a mechanical filter or protein skimmer intake to maximize export of the bound phosphate particulate. Brightwell's basic guidance is 2.5 ml per 20 US gallons daily to remove 0.5 ppm phosphate. Do not exceed 0.5 ml per 4 US gallons daily. If livestock reacts poorly, reduce the dosage by 50% and lower phosphate more slowly. Avoid rapid phosphate drops in aquariums that have remained elevated for an extended period.
