D-D Rowa Phos 250g

RowaPhos is a professional-grade, iron-based filtration media designed to remove phosphate, silicate, and arsenic from both freshwater and marine aquariums. Its chemically engineered ferric hydroxide matrix offers one of the highest phosphate absorption capacities available and does not leach phosphate back into the water once exhausted. By effectively reducing phosphate, RowaPhos helps prevent nuisance algae, supports coral calcification, and promotes clearer, healthier water.

To use, keep the media moist and place it in a filter bag, reactor, or canister with strong water flow for optimal contact. Do not rinse before use. A 250 g pack can treat approximately 1,000 L of saltwater or 2,000 L of freshwater. Once the media becomes saturated, regularly replacing a portion helps maintain optimal phosphate control.
