Only Rowa make RowaPhos and any other iron based material is simply a copy with a completely different chemical structure and properties.

RowaPhos has the largest absorption ability of any phosphate product worldwide and will not leach back in to the water. This saves the need for immediate removal once the media is exhausted. The product is easy to use and will improve the water quality wherever Phosphate or Silicate is a problem.

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.

Constant use of the product is recommended, as its abilities to control nuisance algae is a major benefit.

In an independent series of tests carried out by the Berlin Technical University on the five most commonly used phosphate removers at that time, RowaPhos was found to be the most efficient in removing phosphate from water. Other medias tested reached only to 30 – 40 % of its removal capacity by weight. Additionally RowaPhos was found to continue to remove phosphates at lower concentrations and had a higher maximum holding capacity. 

Since these tests many ferric products have been brought out which ride on the performance of the Rowa product and some even claim to be the same, however RowaPhos UNIQUE and its patented manufacturing process cannot be copied.
