Seachem Reef Buffer is intended primarily for use in a reef system where the maintenance of a pH of 8.3 is often difficult. When used as directed, Sea Chem Reef Buffer will raise the pH of your reef system to 8.3 without fear of accidentally overshooting the pH to a dangerous level.
Sea Chem Reef Buffer is a blended product and is not just sodium carbonate. Reef Builder should be used to raise alkalinity when pH is not a problem. Use Seachems MultiTest: Marine pH & Alkalinity to check pH and total alkalinity. Reef Buffer will also raise carbonate alkalinity.
