Reef Foundation A is a complex of calcium, strontium, and barium, which are the fundamental building blocks for coral skeletons. As a core component of the Red Sea Reef Care Program, it provides the essential elements needed for rapid calcification and healthy coral development. By maintaining stable calcium levels, you ensure your corals have the resources necessary to build their internal structures and grow effectively.
To achieve optimal results, Reef Foundation A should be dosed according to the measured calcium uptake of your specific reef system.
Core Building Blocks: Delivers a concentrated blend of calcium and strontium in the exact ratios used by corals.
Skeletal Development: Directly supports the formation of aragonite for robust coral skeleton growth.
Flexible Formats: Available in liquid form for immediate dosing or as a powder for economical, large-scale supplementation.
Balanced Ecosystem: Works in a coordinated 1:1 ratio with Reef Foundation B (Alkalinity) and C (Magnesium) to maintain the "Stability Triad".
Why is strontium included with the calcium? Strontium is biologically linked to calcium in the formation of coral skeletons. Red Sea includes them in a fixed ratio to ensure both are replenished simultaneously as corals grow.
What is the ideal calcium level for my tank? For a balanced reef, it is recommended to maintain calcium levels between 410 and 450 ppm, depending on your specific goals for growth and coloration.
How often should I test calcium? It is best to test weekly when establishing a dosing routine. Once your tank's daily uptake is determined, you can adjust your Reef Foundation A dose to maintain rock-steady levels.
Red Sea Calcium Pro Test Kit: A high-accuracy titration kit essential for measuring uptake and calculating your exact dosing needs.
Reef Foundation B (Alkalinity): The necessary carbonate buffer that must be used alongside Calcium for skeletal formation.
Red Sea ReefDose 2 & 4: Automate your calcium supplementation to eliminate fluctuations and maximize coral growth rates.
