Tropic Marin Pro-Coral Kalk is calcium hydroxide in its 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 CO2- calcium reactor.
Tropic Marin Pro-Coral Kalk
+ For the active increase of pH value and calcium supply
+ use of calcium hydroxide of the highest purity for the creation of classic lime water as per Wilkens
+ promotes the growth of corals and coralline red algae
+ carbon dioxide is bound, resulting in the reduction of growth of undesirable algae
+ particularly beneficial for aquariums with CO2 calcium reactor, as carbon dioxide is an unavoidable by-product of operating a CO2 calcium reactor
+ also recommended for aquariums with a low pH value
Dosage for Tropic Marin Pro-Coral Kalk:
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.
