Rowaphos Phosphate Remover Media 250 gm

Rowaphos is a professional-grade media that removes more phosphate and silicate than competing products, protecting water quality in aquariums and ponds.

*Media bag Included.

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.

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.

• Capacity: approximately 25 g of phosphate per kg of media
• Typical yield: 250 ml removes up to 3 ppm of phosphate from about 1000 litres of salt water, or 2000 litres of fresh
• Pack: 250 g, media bag included

Setup & Use

A media reactor with gentle upward flow gets the most out of it; the supplied bag in a high-flow area of the sump or the last chamber of a canister also works, just less efficiently.

Rinse briefly in RO water before use. Start with about half the calculated quantity and build up — stripping phosphate from a tank that has run high for months, all at once, is what causes corals to bleach. Bring the level down over weeks, not days.

Keep it damp. Rowaphos is supplied wet and loses effectiveness if it dries out, so close the tub properly if you are not using all of it. Once exhausted it holds what it has captured rather than leaching phosphate back, but it stops working — replace it when your phosphate reading starts climbing again.

Freshness & Storage

Every batch we dispatch carries a minimum of 6 months' remaining shelf life. Store this product in a cool, dry place away from direct sunlight, with the cap or inner foil closed tightly after each use.

Filter media and substrates carry no manufacturing or expiry date — their working life begins on first contact with water, not on the shelf.

Returns & Replacement

Returns are accepted within 7 days of delivery, provided the item is unused and in its original packaging. Manufacturer-sealed items cannot be returned once the seal is broken, and sale-priced items are not refundable.
