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.

Great product for my pool

[This review was collected as part of a promotion.] Alkalinity Increaser is easy to use. It brought the alkalinity level as stated on directions. If you know the amount of gallons you have in your pool and points needed to come up, then this is the product to use. With it being an HTH product, I feel comfortable that it is a safe product. I will be recommending this to my friends.
