### ⭐⭐⭐⭐⭐ Great shock!

Love it! I shock the pool every Monday and it is spotless!!

### ⭐⭐⭐⭐⭐ Recommend
*by J***N on August 30, 2026*

I converted to a saltwater pool this year and this came highly recommended from a friend who uses it and they will write. It’s great. I’ve had no problems that were major of any kind this season and that’s a first in many years.

### ⭐⭐⭐⭐⭐ Works!!!
*by A***L on May 25, 2026*

My pool was swamp green when I took the cover off for the season. Then after cleaning it up it was super cloudy. I read about this stuff and decided to try it. I've used it twice and my pool is now crystal clear. I will be buying more and I even told my friends with pools about it 👍🏽 Super easy to use. It's a little expensive but it's worth it because I was spending money on other things that didn't work.
