PowerPhos is a highly effective phosphate remover designed to enhance water quality in saltwater reef aquariums. It efficiently absorbs dissolved phosphates and silicates, which can otherwise contribute to unsightly algae growth and poor water conditions. Each package of PowerPhos comes with clear dosing instructions: start by using 100 ml for every 80 US gallons of water, then adjust the dosage up to 150 ml as needed over time, but never exceeding 200 ml per 80 gallons. To ensure optimal performance, place the material between layers of filter wool or use a fluidized-bed-reactor setup.
