Lost a bunch of trees due to storms this past winter, pool is getting a lot more sun, and water temps are higher. I was having a tuff time keeping the water from becoming cloudy, thought I'd take a chance and try this. WOW!!! Works great, water is beautiful, clear and sparkling. That said, I FOLLOWED THE DIRECTIONS FOR PROPER USE, I balanced my water chemistry, got the chlorine level to .05 ppm, and added the frog sanitizer to my skimmer basket. The water has stayed beautiful since then, no more cloudiness, despite the higher water temps and lots of direct sunlight. Will definitely use again next year, a bargain for a year of clear clean water with minimal chlorine.
