Review: Good product - This works very well. I deal with high Ph sue to aeration mostly and this product works great. I find its similarly priced to the smaller bags of the Clorox 5lb ph reducer but this has much more. Its harder to store than the bags if you have limited space. Yoi need your own scoop to use this product, it is not included. Overall, no issues.
Review: Dissolves quickly. - Very effective ph control. Dissolves quickly and good value for the money.

### ⭐⭐⭐⭐⭐ So much easier to order it here.
*by L***E on January 15, 2026*

So much easier to order here and have it delivered than to drive to the pool store and pick it up and haul it home. Same stuff, works fine, same solid packaging. Easy is a good thing.
