*Scientific-grade marine aquarium salt replicates natural seawater
*Highly soluble phosphate- and nitrate-free marine aquarium salt
*Contains all essential major and trace elements for aquarium health

Replicate natural seawater chemistry with scientific-grade marine aquarium salt. Coralife Marine Salt is formulated with ingredients of the highest quality with optimal levels of calcium and magnesium. Unsurpassed in purity, quality and performance, this high grade synthetic salt mix contains all essential major and trace elements to help inhabitants of saltwater and marine reef aquariums flourish. Rich in vitamins, this fast-dissolving formula provides enriched seawater environment AND crystal clear water. Phosphate and nitrate-free.

The Coralife Marine Salt Mix Solution
Dissolving 1/2 cup of Coralife Marine Salt in one gallon of purified 78°F water will yield a solution with the following properties:

Specific Gravity: 1.021-1.023
pH: 8.2 to 8.3
Calcium: 390 to 410 ppm
Magnesium: 1,110 to 1.250 ppm

  1. Use dechlorinated tap water, distilled, deionized or reverse osmosis water.
  2. Mix salt in appropriate amount of water - approximately 4 cups to every 10 gallons.
  3. Aerate mixture to attain adequate gas equilibrium.
  4. Adjust salinity (specific gravity) to desired level using a reliable hydrometer. To increase salinity, add salt. To decrease salinity, add water. A specific gravity of 1.021-1.023 is recommended for most marine tanks.
  5. Reseal zip-lock bag and store remainder in a dry place.

Approximately 0.30 lb. of Coralife Marine Salt dissolved in 1 gallon of distilled water at 78°F, will yield a solution with the following properties*:

Specific gravity - 1.022-1.023
pH - 8.2-8.3
Calcium - 430-450 ppm

*NOTE: Test results may vary with different test methods.
