Why Calcium, Alkalinity & Magnesium Matter

Growing corals continuously consume calcium, carbonates, magnesium, and other elements from aquarium water.

Maintaining these foundation parameters at stable, balanced levels helps support:

Coral skeletal growth and calcification

Stable alkalinity and water chemistry

Healthy SPS and LPS coral growth

Coralline algae growth

Consistent reef aquarium conditions

Balanced supplementation based on your aquarium's actual consumption

Designed for Measured Reef Dosing

The Red Sea Reef Foundation system allows calcium, alkalinity, and magnesium to be monitored and adjusted individually based on the needs of your aquarium.

For best results, regularly test your aquarium's calcium, alkalinity, and magnesium levels and dose according to measured consumption. Avoid dosing supplements simply to reach a target without testing.

Pair with the Red Sea Reef Foundation Pro Multi Test Kit for accurate monitoring of all three foundation parameters.
