Reef Salt™ is a chemically sound blend of salts designed to replicate natural reef waters. It is specifically formulated for the reef environment and will provide ideal seawater concentrations of magnesium, calcium, 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 contains no toxic or non-essential components such as nitrate, phosphate, silicate, arsenic, cadmium, or beryllium. Reef Salt™ dissolves quickly and completely and is ready to use in only a few minutes. 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).
For marine only environments, use Seachem Marine Salt™ instead. It is specifically designed to meet the requirements of a marine only (not reef) system.
USAGE NOTE: NEVER mix salt in an aquarium containing animals. In New Aquariums: Transfer animals to the aquarium AFTER salt is completely mixed and aerated and specific gravity has been adjusted. Use Seachem’s Stability® to avoid “new tank syndrome” and prevent unnecessary animal losses in a new system.
NOTE: Depending on specific gravity, alkalinity should be about 4.0–5.0 meq/L, calcium should be between 380–430 mg/L, magnesium should be between 1200–1350 mg/L, and strontium should be 8–12 mg/L. Between water changes some elements may become depleted through utilization. Seachem offers a full line of reef supplements for restoring and maintaining many parameters, including (but not limited to) calcium, magnesium, strontium, iodide and alkalinity.
