So fast you're head will spin. Review by Leigh
We just ordered this shock yesterday at 3pm, and it came today at 12pm! Wisconsin to Indiana in a blink. I don't know how they do it, but it's impressive don't ever change Doheny's! The shock clears the pool in minutes.
This is the best shock Review by Mommawlilbear from NC
You'll never have any problems if you use this by the directions. We've had some pretty bad looking water from rain, and after a couple applications and vacuuming it cleared right up.
Pool Shock Review by Rick
Take care of my Mom's pool and all of 2013 I wrestled with yellow algea and so I put this shock in and in one day the pool was clear and the yellow algea has not come back. With the quality and low price of your shock I will not go back to store bought. Also shipping was on time.

Great Product Review by Kathy
We have been having so many problems with algae this year for the first time. Rain then hot and humid so often the pool greened up and looked bad. We used 2 the first day then 2 more the second day and the algae was gone and the water crystal clear. We now have to do it again after 2 weeks as the weather is just reeking havoc on the algae again. But this stuff really works - we're so happy we tried it.
