Pool Mate 1-2210B pH Up for Swimming Pools, 10-Pound

No complaints works as expected

I tried for weeks to raise PH in pool nothing was working. One dose of this product and PH is now where it needs to be. 😃 plenty left over for the rest of season and probably next summer too.

Works just as well as the competition but cheaper.

I’m happy with the product, price and delivery option. Beats expectations. ONE CAUTION: instructions say to pre-dissolve in a bucket, you can but only a few hours, and it doesn’t really seem to work well , try overnight and it will all turn into a brick. So I just power thin layers into the deep end with the pump on….

Is perfectly engineered to achieve water safety.
