You can feed your fish and not your algae ROWAphos is the professional way to control nuisance algae in freshwater and marine aquariums. It absorbs phosphate, silicate and heavy metals from the water column without releasing any back into the tank when fully saturated. It can be left in the aquarium indefinitely with no ill effects.
Using a patented manufacturing process Rowa has produced a unique iron hydroxide based compound which is unlike any other iron based product on the market. It has a distinct crystal structure and high porosity/surface area which gives it an unrivalled ability to bind phosphates to its surface.
Absorption capacity of ROWAphos is 25g of phosphate per kg of media
