Tropic Marin Pro-Coral Kalk is calcium hydroxide in ist purest form and is used to make up the classic limewater advocated by WILKENS. Tropic Marin Pro-Coral Kalk increases pH and calcium content to promote the growth of corals and calcareous coralline algae. It inhibits the growth of undesirable algae by binding carbonic acid, one of the inevitable by-products of operating a CO˛- calcium reactor.

Add one measuring spoon (10 ml) to 5 litres of reverse osmosis water and mix by stirring or shaking the container. Do not aerate ! After the undissolved lime has settled, slowly pour the remaining clear solution into a well-flowing area in the aquarium, preferably one drop at a time. Prepare fresh limewater every day. The water which has evaporated can be replaced on a daily basis with limewater. When filling the tank, check that the pH level does not exceed 8.4 as this can lead to precipitation. Ideally, limewater should be added at dusk or shortly after dark as this is when the pH in the aquarium is at its lowest. The pH level in the aquarium at night should ideally not drop below 7.9.
