RowaBac has been carefully developed for the starting or enhancing of denitrifying bacteria and stabilising the biological equilibrium within saltwater and freshwater aquariums. As a start-up addition the bacteria will rapidly accelerate the maturation of the system through the nitrogen cycle and as a maintenance dose RowaBac will boost the levels of reducing bacteria to remove nitrates from an established aquarium. By regularly using RowaBac your water quality will improve greatly through the reduction of ammonium, ammonia, nitrate and nitrite levels. This product is also useful for repairing the biological equilibrium following filter cleaning, water replacement and medicinal treatments. Please refer to the product guidelines for the amounts to use and the optimum frequency of use. 100ml of this product will treat 1000 litres of tank water at start-up.
