The ultimate phosphate removal media for freshwater and saltwater aquariums. Originally developed in Germany to treat water supply mains, this unique and patented ferric hydroxide media is chemically engineered for efficient removal of phosphate, arsenic, and silicate. Rowaphos binds aquarium pollutants and does not release phosphate back into the water even when exhausted. Increased concentration of the aquarium pollutant phosphate can contribute to unwanted conditions including aggressive nuisance algae growth and inhibition of calcification in such marine organisms as calcareous algae and hard corals. Use Rowaphos to effectively remove phosphate and improve aquarium water quality. The binding (adsorption) capacity of Rowaphos is approximately 25 grams phosphate per kilogram of media.
