Our Coral Essentials, Chroma+ is a blend of water soluble, complex organic coenzymes. It aids in the catabolism of sugars and amino acids as well as supporting many metabolic processes. The multiple coenzymes in our formula are essential for many enzymatic reactions supporting all animal life. Chroma+ brings your coral to life, colours pop and radiance is improved. Noothing gives your tank a colour boot like Chroma+. As it is an organic water soluble product, excess Chroma+ not used in the tank is easily removed through standard organic waste processes and skimming.
