Salinity – 225 gal

salinity is a blend of salts specially formulated for the reef aquarium that contains all essential major, minor, and trace components found in natural reef waters, but contains no toxic or non-essential components. Additionally, salinity is the most concentrated salt blend on the market. With a hydration level of <0.5%, salinity will yield a greater volume of prepared saltwater at a salinity of 35‰ per unit of weight than any other salt mix currently on the market. salinity is identical to the distribution of anions and cations found in Natural Sea Water (NSW). Guaranteed to be within ± 5% of the midpoint range for the following elements:

Calcium: target 422 mg/L, range 400 to 443 mg/L
Magnesium: target 1334 mg/L, range 1269 to 1403 mg/L
Strontium: target 8.4 mg/L, range 8.0 to 8.8 mg/L
pH: 8.4 to 8.6
Alkalinity: 3.2 to 3.8 meq/L
