With elevated levels of ionically balanced key macronutrients such as alkalinity, calcium, and magnesium it was designed to keep up with even the most nutrient demanding and rapidly growing coral colonies.
 
Unlike the natural reef environment with abundant levels of micro and macronutrients,  an aquarium is a closed ecosystem in which valuable micro and macro trace elements are constantly being consumed by corals at different rates. Continuous access to macronutrients is one of the most important aspects of keeping a healthy and stable reef aquarium. For those not dosing microelements individually, regular water changes with Reef Salt + will help provide these valuable elements back into the water at a balanced ratio for corals to absorb and aid in their growth, coloration, and immunity.
