Red Sea Reef Foundation is based of years of biological analysis of corals and what they intake when they grow. From their results, they have been able to formulate the Reef Foundation system for Calcium, Alkalinity, and Magnesium maintenance in reef tanks. Using ultra pure raw products, Red Sea has packaged the additives in ready to use bottles and jugs that you can dose directly out of with no mixing required.


Dosing Instructions: 1 mL will raise the alkalinity of 25 gallons by 0.036 meq/l (0.1dKH)


Reef Foundation A - Calcium and Strontium

Reef Foundation B - Alkalinity

Reef Foundation C - Magnesium


For a complete trace element system, we recommend using Red Sea Coral Colors A, B, C, & D along with the Reef Foundation System.
