A must-have for the serious reef aquarist. Seachem's ReefSalt mix dissolves quickly and completely, ready to use in mere minutes, and is specially formulated not only to keep your reef in optimal health, but also to promote coral and invertebrate growth beyond other salt mixes. Used as directed, it will buffer and maintain a pH of 8.4 between water changes, providing superior calcium and alkalinity stability.
ReefSalt mix provides ideal concentrations of calcium, magnesium and strontium with proper alkalinity and pH for closed reef aquarium systems. It contains all essential major, minor, and trace components found in natural reef waters, but no toxic or non-essential components such as nitrate, phosphate, silicate, arsenic, cadmium, or beryllium.
Reef Salt will support and promote enhanced calcium and alkalinity stability for those wishing to maintain calcium above Natural Sea Water (NSW) levels (400 mg/L) as well as providing NSW levels of bromide (65 mg/L).
