HTH 52035 Swimming Pool Care Shock Advanced, Swimming Pool Chemical, Cal Hypo Formula, 1lb

The product performs exceptionally well. After a significant rainstorm caused my pool to flood and become quite dirty, I added two bags of the product, and within just two hours, the water was already starting to look clear again.

A well known product that has a history of working well in the set up of our pool. Does not leave a residue or heavy smell. It makes our skin soft and not tight. It also has ingredients in it that are great for aging skin!

It’s easy to use it’s does the job long lasting crystal the ph is good as well definitely removed the stains

Honestly, one of the best shocks for your buck. It is pretty cheap for what it does. It dissolves fairly quickly, easy to open, clears up the pool in an hour or so, and it last for a few weeks.

It works like the rest of the pool shock. It cleared up my pool and then it also got rid of the slime pretty good too

One of these bags clears up my whole inground pool within a half hour. Rarely need to use it, but when I do, it does the job.

Ok, here we go... So I live in Florida, so everyone here knows how hard it is to keep your pool from turning green... This product works great. I use a bag a week, with my normal chlorine and no green.... I liked it enough to buy it again. Great people, and a great price... Happy camper here.

Great product, never have any problems. Keeps my pool crystal clear.
