Product Information
Remove phosphates and promote plant and coral growth with this treatment. Best price guaranteed and fast, free delivery from Swell UK.
RowaPhos is a great filter media that will rid your aquarium of phosphates, traces of arsenic and other unwanted elements. Phosphates and nitrates especially are key causes of algae growth, which can be a real nuisance.
Corals can suffer too, as a high level of phosphates can reduce the amount of strontium which corals calcify for healthy skeleton growth.
Unlike many similar treatments, RowaPhos is chemically engineered to remove phosphates and other pollutants, it has been found to work much better than more natural, iron based treatments.
Good tank maintenance is also key to keeping algae growth to a minimum. Waste food, fish and plant waste will produce ammonia and phosphates very quickly. Remove uneaten food after a few minutes and keep the tank and filter as clean as possible.
Please note only the 100ml and 250ml tubs come with a net filter.
