Member's Mark Quick Dissolving Shock 20lb with 10 Test Strips

Much easier to use than liquid chlorine and also includes stabilizer.

Easy to use

Great shock!   The only shock I use in my unground pool!!

Great product!

Great product. However getting too expensive!

Price getting too high

All the packages were not sealed properly and granules spilled out

Needs better quality control

Very dependable!!

Good product

This pool shock has kept our pool clear throughout the year. Best one we’ve used.

Pool Shock

Works well

Great buy. Just what I wanted to keep my pool clean - works great

Great buy

Happy

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
