Seachem Reef Buffer 250gm / 8.8oz
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, Reef Buffer will raise the pH of your reef system to 8.3 without fear of accidentally overshooting the pH to a dangerous level. Reef Buffer will also raise carbonate alkalinity. 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 Seachem’s MultiTest: Marine pH & Alkalinity to check pH and total alkalinity.

I’ve used Reef Buffer in my 120-gallon reef tank for several months. It consistently brings the pH to 8.3 without spikes. The alkalinity also increases steadily, which helps maintain stable conditions for corals. Easy to dose and effective after testing with MultiTest.

The product works well for raising pH in a sensitive reef setup. I noticed a gradual increase in alkalinity, which is good for long-term stability. I still use MultiTest to monitor levels regularly.

After switching from other pH adjusters, Reef Buffer has given me consistent results. No overshoots, and the system remains stable. I appreciate the blend formula—it doesn’t just raise pH, it supports alkalinity too.
