My pH had drifted higher than recommended, and after following the dosage instructions, I noticed improvement within a short amount of time. The water looked clearer, and it felt much more comfortable for swimming afterward.The granules dissolved well when added properly, and the packaging was sturdy and easy to reseal between uses. I also appreciate that the instructions on the bag are straightforward and easy to understand, even for routine maintenance.One thing I liked is that it allowed me to make gradual adjustments without overcorrecting the water chemistry. After testing again later, the pH levels stayed in a much better range, which also helped the chlorine work more effectively.Overall, this has been a dependable pool maintenance product from a brand I trust. It’s easy to use, effective, and a useful item to keep on hand during pool season. ### ⭐⭐⭐⭐⭐ Lowers the pH quickly! *by on Reviewed in the United States 19 August 2026* This stuff works great! Went from 8.3ph to 7.7ph in a matter of days. Depending on the size of your pool, you may need more of it than you think. I initially put one bag in over 24 hours in an 18,000 gallon salt pool and needed half of another bag to get it the proper level. I think adding a cup or so each week will prevent the pH from spiking. ### ⭐⭐⭐⭐⭐ Works well *by on Reviewed in the United States 26 August 2026* Did the job.
