Calcium, magnesium, strontium and carbonate are the basic foundation elements of coral skeletons. All of these elements need to be available in balanced proportions for positive coral health and growth. Reef Foundation ABC+ is a blend of all of the foundation elements with the addition of potassium, bromine and iodine in the unique ratio required by corals.
Red Sea’s Reef Foundation ABC+ is a uniquely formulated powder supplement containing all of the elements of Foundation A, B & C, plus Red Sea’s Coral Colors A & B (potassium, boron, iodine & bromine) formulated in the exact ratio as found in the coral skeleton.
Although there are slight differences between the coral species, the mean ratio between these elements is fairly constant. Supplementing all of these elements in a fixed ratio according to the uptake of calcium will ensure an accurate replenishment based on the metabolic demands of the corals.
Reef Foundation ABC+ should be dosed on a daily or weekly basis according to the aquarium type and according to a measured uptake of calcium. Over time an imbalance may occur between the foundation elements.
If dosing daily, you should test all of the foundation elements weekly and make adjustments with the individual A, B & C supplements. If dosing weekly you should test all of the foundation elements monthly and make adjustments with the individual A, B & C supplements.
