Red Sea Reef Foundation B (KH/Alkalinity) Powder 1kg

Carbonate & buffer complex for balanced formation of coral skeleton. A successful coral reef aquarium depends on maintaining appropriate water parameters that provide the stable environment corals need. While all elements in natural seawater play a role, three major elements form the foundation: Calcium (Ca), Magnesium (Mg), and Bicarbonates (HCO3). These elements significantly affect water chemistry—pH stability, alkalinity, and ionic strength—and support critical coral biological processes including skeleton formation, ion exchange, and photosynthesis. The foundation elements work together in coral skeleton formation. When not available in correct ratios, one quickly becomes the limiting factor for healthy coral growth. Red Sea Foundation B (Alk) is a complex of carbonate and buffer compounds that maintain proper alkalinity and pH. Just 1ml raises the alkalinity of 100L (25gal) by 0.36 meq/L (1dKH). This 1kg powder provides reliable, consistent dosing for stable reef conditions.
