Suitable chemical is a mixture of salts designed to replicate the marine environment. It is specifically designed for the average reef and provides ideal concentrations in seawater magnesium, calcium and strontium with proper alkalinity and pH for reef aquarium systems closed. It contains all major components, minor and trace elements found in natural sea water reef, but contains no toxic or non-essential components such as nitrates, phosphates, silicates, arsenic, cadmium or beryllium. Reef Salt dissolves quickly and completely and is ready to be used in only a few minutes. Salt Reef supports and promotes the stability of calcium and alkalinity needed to maintain calcium levels around (400 mg / L) appearing in the natural seawater, as well as levels of bromide (65 mg / L).
