Great product! Our pool is clear for the next day after shocking it at night!

Very dependable!!

Started using in June and could not figure out why algae was worsening. Should have read the reviews. The more I added the worse the algae became. Will be returning it.

Made algae worse

Works very well, used it for a few years but due to COVID, got into using calcium hypochlorite type stuff, big mistake. After a complete cluster on opening this year, finally got the pool looking right by abandoning Calcium based shock and going back to this stuff.
The only downside is the incredible price rise over the last 2 years, way beyond what I would have expected even given our rampant inflation.

Excellent stuff, glad to have come back to it
