Great product!
Would Recommend[This review was collected as part of a promotion.] I have really enjoyed this product since it's arrival. It works as expected and is very easy to use when balancing our pool chemicals. It did a great job of helping get our alkalinity level under control after we had a balance issue.

Safety
Would Recommend[This review was collected as part of a promotion.] Many have told me to test pool water for alkaline amounts. I have a local pool company to tests water at their facility - so they have advised me that your pH should be between 7.2 and 7.8 and the alkalinity should between 110 and 150 ppm, not sure what this means, however they will advise me when I need to use the Alkalinity Up.

Works Great!
Would Recommend[This review was collected as part of a promotion.] I tried out the HTH® Pool Care Alkalinity Up and it works great. My father-in-law has an in-ground pool and he was very sick. I bought this among others to help him get his pool back in order. I have never used these products before. The instructions were easy to understand, and I was able to clear up the pool and get it back in order. I highly recommend this and would definitely buy again.

Happy swimmers
Would Recommend[This review was collected as part of a promotion.] I religiously test twice a week with a 6 way test and adjust as necessary. I trust HTH Alkalinity Up to adjust my water to safe levels for my children to swim. I also use it to keep the wear and tear on my filters and equipment to a minimum. Acidic water can eat away at the filters, hoses, pumps and tiles over time and Alkalinity Up helps reverse it before it causes damage. Pools take work and HTH helps make it easier.
