Tths pool shock worked well and helped clear up the water quickly. It was easy to use and a good price for pool maintenanc.

This has been the best pool shock I've ever used. Has made keeping my pool clean and clear a breeze. The price is good too!

Works great as a shock treatment without a doubt, 5 stars for the actual treatment part. But be careful of the granules. I didn't think (I usually buy the finer powder), and scattered my 1lb around the pool as normal, and went on my merry way. In the morning I saw where it touched/settled on the pool floor, the floor went black. It was a pretty permanent stain, that lasted months. I now feed slowly through my skimmer instead of pouring directly in, and only get occasional staining. Works well though, I wouldn't use less hyperchlorate % than this, and I like the brand, quality is consistent as is the product. I do prefer the powder version though honestly.

Great value! We can go to other big box stores and pay more. I trust this beans and I can read what’s actually in the shock.

Shock has helped the pool go from green to blue (check photos). Good product that works quickly (12 hours)

Its what I need, and it works well. Its not as high a concentration as you can get at pool and spa stores, but its also not as expensive.

Great packaging individually packed in a box or 12. High concentration of 68% cal hypo. Works great for our pool, kills algae right away and helps maintain crystal clear pool. Highly recommend!
