RowaPhos Review

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 salt water, having initially been developed in Germany for treating mains water supplies.
It is of interest to Marine and Reef Aquariums where its unrivalled capabilities have shown it to be extremely beneficial in the control of nuisance algae’s and the growth of hard corals.

Like Phosban, Rowaphos is made of ferric oxide hydroxide rather than aluminum oxides. Aluminum oxides does remove phosphate, but isn’t ideal for a reef tank because it often leaves enough phosphate in the water for nuisance algae and it contains aluminum.
Rowaphos is wet with a caviar-like appearance. The manufacturer recommends keeping the material moist and the container tightly closed.

Rowaphos is really effective at lowering phosphate levels in a reef tank and can reduce them to natural seawater levels. Howerver, I tried it once and see no (or maybe little) difference in effectiveness of the two leading brands: Phosban and Rowaphos. Both product can be used depending on price and availability.

Flow rate is important. It will not receive enough flow by having it in a media bag. Not enough flow will cause it to “clump up” making it less efficient. For that reason, you should definitely get a reactor. A Phosban reactor will do the job. A reactor allow you to push about 80-90 GPH through the Rowaphos which is I think the best flow rate.
