### ⭐⭐⭐⭐⭐ Quality product
*by A***T on August 25, 2026*

Price is fair and it's a effective item. My pool is about 16000 gallons and 1 bag a week works fine unless we get a lot of rain. Don't be concerned with the quality.

### ⭐⭐⭐⭐⭐ Best price for shock
*by E***6 on September 11, 2026*

Great price for quality pool shock.

### ⭐⭐⭐⭐⭐ Good stuff
*by J***L on June 26, 2026*

Used this stuff for the last two years. The trick is to dilute it in warm or hot water and let sit for about ten minutes then stir it with a stick then pour. It will get cloudy for about one to two days depending on how much you used. I like the cloudiness because I can see the chlorine circulation.
