$27.99

Complete Powder Supplement Ca/Sr/KH/Mg/K/Br/I

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.


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.

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.
