Red Sea Foundation™ A Calcium+ (Ca/Sr/Ba)

Red Sea Foundation™ A Calcium+ is a highly concentrated blend of Calcium, Strontium and Barium—the essential foundation elements required to build strong, healthy coral skeletons. Formulated to maintain the exact ratio these elements are naturally consumed in, Calcium+ ensures stable, balanced chemistry in modern reef systems.

As part of Red Sea’s Reef Care Program, Foundation A supports rapid coral calcification, prevents fragile or brittle skeletal growth, and helps reefkeepers maintain long-term stability with precision and ease.
