Lime washer or lime water, translated from German, is one of the oldest methods of adding calcium to the reef aquarium. It has proven its usefulness: corals experience a better and stronger growth, without any side effects.
ROWA lime consists of 98.2% pure calcium hydroxide, for making lime water (lime washer) and for use in lime water (lime washer) stirrers. Lime washer is a solution made by dissolving calcium hydroxide in water. The fresh solution obtained is alkaline with a pH of 12.4 and contains an easy supply of both calcium ions and carbonate ions. Both ions are useful in the aquarium: carbon to buffer pH levels and calcium for the corals. Lime washer alone does not contain other ions that would cause an imbalance in the water chemistry of the aquarium. Add the lime scrubber with great care: it is highly reactive with CO2 and can change pH levels significantly if not used and controlled properly. Please consider using a lime washer stirrer.
