Pool Shock

Chlorine shock

bought for back up to tablets which are way out of sight for price right now.

good price available

Works great!

Price has increased almost three times from two years ago.

Outrageous prices.

Works great

Good shock

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
