Aquaforest Ca Plus is a highly concentrated formula designed for raising calcium levels in marine aquariums. Calcium is a vital element for coral skeletal formation and growth. Ca Plus supports calcification and healthy coral growth by providing easily assimilable calcium during shortages or sudden drops in your marine aquarium. The effectiveness of Ca Plus supplementation depends on the proper KH level, therefore it is recommended to use products that raise carbonate hardness (KH Plus or KH Buffer).
