Clorox Xtra Blue 40 Pound 80 Tab Pool and Spa 3 Inch Long Lasting Chlorinating Tablets

This year (2018) was the first year we used this product from beginning to end of summer. We had a BRUTAL summer in the Mid-Atlantic region with excessive (and overwhelming) heat as well as periods of intense rain. Our pool was clear ALL SUMMER LONG! I attribute our water's appearance to this product. No need to change or check other brands when we have no issues with what we use. Awesome!

These chlorine tablets far exceeded expectations. They left the water feeling like I was in a newly filled pool. The water was extremely clean and algae free until the tablets ran out- which was in at least three weeks. [This review was collected as part of a promotion.]
