This product raises carbonate alkalinity without having an immediate impact on the pH. When used for a long period of time there is a tendancy to stabalize at 8.3 pH. Carbonates and calcium are essential to coral growth. Growth will cease if either becomes deficient. If used as directed, this product will not deplete calcium, magnesium or strontium which usually tends to precipitate with increasing alkalinity.

Instructions: Use 1 level tsp per 40 gallons of water twice a week. Dissolve in at least 1 cup of freshwater. Make sure to check alkalinity every 2 weeks and adjust dose accordingly.

Ingredients: Carbonate, bicarbonate, chloride and sulfate salts of sodium, magnesium, calcium, strontium and potassium. Each gram contains a minimum of 12 meg of alkalinity.
