I’ve used this buffer for several months now and it’s made a big difference in stabilizing my reef tank’s pH. My corals have shown better color and growth since I started using it regularly. Easy to measure and effective without causing spikes.

The product works well for maintaining pH in the 8.2–8.4 range. I added it once a month after testing the water. It doesn’t overcorrect, which is a relief after some previous issues with pH swings.
