HTH 52005 Super Shock Treatment Swimming Pool Cleaner, Single

Even though we have a very good well filtration unit, about twice a year it just gets too much rust bacteria. . . and this is a great way to clean it. Start off with clean filters and in about a week change them out again. Water is not drinkable for about five days so plan ahead by storing water. No washing clothes for about three days also. After treatment water is super clean and very tasty.

I liked how quickly the product worked. I used it for the back yard pool to kill the algae in the pool

I liked the product, I'm a first time pool owner and it was super easy to use, just open and pour and let it work.

Clicked on to buy 6 bags of this pool shock. Something happened and my order shows ordering one bag for $23.00????? I think the problem is if you click on other boxes, the results goes back to the 1 item box and in my case I didn't realize it. Who would order just one bag of shock for their pool? Pool owners want 6 or 12 bags. Total ripoff to even have the option of one bag. This brand is a very good brand but the customer needs to be very careful when placing an order with this seller.

Better than Clorox by far. More expensive and harder to find but worth it
