This product is intended primarily for use in a reef system where it is often difficult to maintain a pH of 8.3. Reef Buffer will raise the pH to 8.3 without overshooting the pH to a dangerous level. It will also raise carbonate alkalinity. This product is a blended product and is not just sodium carbonate. Reef Builder should be used to raise alkalinity when pH is not a problem.

Treats 2000 gallons of water.


Package Size8.8 oz.
Treats up to2000 gal.
pH Range8.3
Internal Id


Contains: proprietary blend of powdered carbonate and bicarbonate salts.


Directions: Check pH and alkalinity before use. Use 5 g (1 level teaspoon) for every 150 L (40 gallons) to raise pH by about 0.1 pH units (this will also raise alkalinity by about 0.5 meq/L). Dissolve in at least one cup of freshwater, then add to the tank. The pH of natural sea water is 8.25–8.30. In a well established reef system pH adjustment may be necessary biweekly to semiweekly. Dosing requirements will vary, but do not exceed the recommended dose without checking your pH and alkalinity (alkalinity should not exceed 6 meq/L). If an alkalinity of 6 meq/L has been reached and a pH of at least 8.20 has not been attained or substantial cloudiness that does not clear within 15 minutes is encountered, then the system is not ionically balanced. To restore ionic balance perform a water change or adjust the magnesium and calcium levels to approximately 3:1 Mg:Ca (calcium does not need to exceed 400 mg/L).

DO NOT OVERDOSE: Excess alkalinity may enhance the loss of calcium, magnesium, and strontium. Do not directly mix with any calcium, magnesium, or strontium supplement.
