Red Sea Reef Foundation™ Calcium+ (Ca+) Red Sea Calcium+ is a highly concentrated calcium supplement designed to maintain optimal calcium levels in reef aquariums. Calcium is an essential element for the growth and skeletal development of stony corals, coralline algae, clams, and other calcifying organisms. As part of Red Sea’s Reef Foundation program, Calcium+ helps replenish calcium consumed by your aquarium’s inhabitants, promoting healthy growth, vibrant coloration, and strong skeletal structure. The liquid formula is easy to dose manually or through an automated dosing system and is formulated to maintain proper ionic balance when used alongside alkalinity and magnesium supplements.
