Doheny's Super Pool Shock | Pro-Grade Chlorine Shock, Quick-Dissolving, Fast-Acting 68% Cal-Hypo Granular Pool Shock | 6 x 1lb Bags, Proudly Made in The USA

This is a great product...I have been using a popular brand of shock for my pool...I switched to these last year and for the money they are much cheaper and work just as good... great product...I will continue using these along with the 3" pool pucks...

I use these as my everyday chlorine. 3oz's a day in a 15x24" pool work great. Pool is in sun all day and I do not need any stabilizer. For some reason buying the 24 bags is much less costly than buying the 25lb pail.I have been using only Cal-Hypo for 8 years now and much better consistent results than using stabilized chlorine.I never empty the pool, so I believe the stabilized chlorine CYA builds up over time and causes the chlorine to not work properly. This doesn't happen with Cal Hypo based chlorine.

We used it for the first time last week and it worked as well as the one we were buying from the pool store. The best part is it’s half the price.

My pool went from dark green to clear in a few days. Will be buying in the future.

Have a 18 x 54 semi above ground pool. Took 4 bags and two days but the green is gone and the pool is crystal clear.

Good price, shocks pool as intended.

This product works great and comes at a great price Delivery was fast and prompt. This is an all around Excellent Product!!

As expected and ready to use
