Feed Your Fish and Not Your Algae.
Rowaphos is the professional method of removing Phosphate and  Silicate in all types of Aquariums and Ponds. RowaPhos is guaranteed to  remove more phosphate than any other product worldwide.
In freshwater or salt water aquariums phosphates will feed nuisance  algae which can overrun plants and expensive corals spoiling the  aesthetics of the tank and in extreme cases killing its inhabitants.
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 salt water, having initially been developed  in Germany for treating mains water supplies.
RowaPhos should not be confused with natural materials, which are  generally based on aluminium oxide, (zeolite) or even other iron based  products which claim to be the same product from other manufacturers.
Why RowaPhos?
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.
