Review on Seachem Reef Buffer - 500g: 🐠 Boost Your Reef Tank's pH and Alkalinity by Sarah Black

By far the best buffer I've found. My PH never exceeds 8.32, even right after taking it. I usually use it every two weeks to maintain pH. I use Neptune Apex for monitoring and charting. I started using it due to a drop in my pH (I don't do regular water changes) and I saw an immediate change in coral expansion for both LPS and SPS. Very happy with the stability over time.
