Keep carbonate alkalinity stable for strong coral calcification with Red Sea Reef Foundation B – Alkalinity (KH), a concentrated liquid supplement for reef aquariums.
Alkalinity plays a critical role in coral calcification, skeletal growth, and overall pH stability. As corals, coralline algae, and other calcifying organisms consume carbonates from the water, Reef Foundation B replenishes these essential elements to support healthy growth, vibrant coloration, and long-term reef stability. Suitable for manual or automated dosing, and designed to be used alongside calcium and magnesium supplements as part of the Red Sea Reef Foundation program.
All livestock ships via FedEx Priority Overnight, double-bagged and temperature-protected with a heat or ice pack as needed for your destination.
Florida orders under $299 ship for $25; out-of-state orders under $299 ship for $40. Orders over $299 ship free. We don't currently ship to Alaska, Hawaii, Puerto Rico, or outside the continental U.S.
