Seachem Reef Buffer – 500 g

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. Reef Buffer is specifically designed to meet the needs and requirements on the closed reef environment. 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.
