Fluval Sea Calcium is a concentrated form of calcium that's easily absorbed by corals and other invertebrates. It helps develop a strong skeletal structure, while not affecting the delicate ionic balance in marine aquariums.

Fluval Sea Calcium contains USP (Pharmaceutical) Grade calcium chloride, ensuring that you're getting a high quality and ultra pure product that's free of unwanted contaminates. It does not contain gluconates, nitrates, phosphates.
