Works as it should

We got hth pool strips that we dunk and take a picture of and it'll tell us where our levels sit and if we need to bring any levels up. If they aren't where they need to be it'll give us suggestions for what we need and how much. This was purchased because of that and works great.

5 out of 5 stars review

This is perfect!!!

[This review was collected as part of a promotion.] I absolutely love the purity of this product. I am always looking for the purest option for me and my family, and this is 100% only ONE ingredient, and it's natural!!! This is part of a system to treat pools, and it raises the alkalinity of the water. This product is number one in the system, and I'd highly recommend this over other products with synthetic chemicals, because this has none. The instructions are right on the big bottle,and clear and easy to follow, and it even has instructions for what else to buy to make your pool healthy,including a "test to swim" app, to ensure safety! This makes me see how this company wants safety for my family just as much as me! I'd recommend this product highly!!!!
