Feed Your Fish and Not Your Algae.
RowaHhos is the professional method of removing Phosphate and Silicate in all types of Aquariums and Ponds.
Within the reef aquarium, phosphates will greatly affect the formation of coral skeletons by reducing calcification by over 50% and by inhibiting the deposition of strontium. It is suggested by Borneman that phosphates are a direct poison to calcification.
RowaPhos is a unique and patented, man made ferric hydroxide material chemically engineered for the efficient removal of phosphates, arsenic, and silicates from fresh and saltwater and for treating mains water supplies.
