Seachem Reef Buffer will also raise carbonate alkalinity; however, it is intended primarily for use as a buffer in a reef system where the maintenance of a pH of 8.3 is often difficult. When pH is not an issue, Reef Builder should be your first choice for a carbonate alkalinity supplement. Reef Buffer is specifically designed to meet the needs and requirements of the closed reef environment.

• Raise pH to 8.3
• Use one level teaspoon for every 40 gallons to raise pH by about 0.1 pH units
• In a well established reef system pH adjustment may be necessary bi-weekly to semiweekly
