This is chlorine and not SHOCK.. I searched Shock and ordered it a but it's unusable chlorine. It's granulated so it does not work in a normal pool. Above ground should be fine.

Excellent value for the money. Works as well as more costly name brands.

nice clear pool easy to use

Excellent deal. Came very quickly.

I have been using this product for the lst 3 years. It works great and is reasonably priced

Worked Fast and Cheaper than most. Well worth the money and value.
