Please see before and after photos. Absolutely remarkable. As soon as you use the shock it clears your pool up within minutes. Nice crystal clear water and I didn't even add algaecide yet. I'm very impressed by this product. Thank you!! Will buy again in the future. My pool is 7000 gallons and I followed the very simple instructions that came with the basic start up kit. ... show more

This is the third year I have ordered and used this product. Although I didn’t use this package yet I wanted to make sure it was known how quickly this order came. It was not supposed to come until Monday May 6th and showed up the day after I ordered it. This product is amazing. Always makes opening my pool easy. The water turns crystal clear! ... show more

Followed directions it worked great. Our filter was having problems last year. So it was a mess opening but thanks to this product clean out was easy. Highly recommend

    • Not dummy proof
Style: Kit Only Size: Basic - 7.5k gallon
I wish the instructions were more clear on how to use. I thought it would be good for someone who didn't ever have a pool before but I didn't know exactly how to use it in our 1000 gallon pool. Based on what I read it wouldn't be good to use the whole packet but I believe it would have been ok and actually allowed us to get our levels to where they should have been. It is a great value but better for someone smarter then me to use I'm sure ... show more

For the price I was skeptical. 24 hour difference. Used as directed. Then let the pump run 8 hours. Need to vacuum once everything settles to clear the fog up but I couldn’t wait to leave a review. Very pleased.
