HTH Chlorine Shock — Granules, 13.3 oz — Pool Shock Treatment for Weekly Chlorination

My pool had a little green starting on the bottom. I used some of this and brushed the bottom and it never came back.

A great substitute for liquid Chlorine. No mess, no smell, easy application. Container is light and easy to carry. Pool water is very clear.Will not stain you clothes or burn your eyes like liquid chlorine.

great pool shock keeps the pool clear clean.

Works like it should! Pool care made easy!

I use these every season to prepare my pool for the summer. It clears the water.

THIS HAS ALWAYS BEEN MY GO TO! GREAT VALUE FOR THE PRICE!

This product does what it is supposed to do however the cost is ridiculous compared pre covid prices. I believe that all these pool products are priced too high and taking advantage of people.

Not as good as liquid Chlorine

i always use this brand, but this particular 6 pack must've been old or not stored properly the granules didn't sink nor help my pool.. just got a new pack from another seller and it was much better. i used them not even thinking about it, until it was too late.

I bought 6 to last several weeks. My pool requires 2 packets at a time on a weekly basis, but I was starting with a greenish water and anticipated the need for additional shock. I put in 2 in the evening with the pump running continually. In the morning, it was overcast and raining, but the 2 packets of shock didn't touch the clarity of the water at all. I tested my PH, CYA and the rest of the levels. My PH was too high, but CYA looked perfect. I added a SUPER Algaecide, PH balancer and 2 more bags of shock. Still green and it still says that is no free chlorine in the water. Basically, I used all 6 bags of shock and did not see any results. Don't waste a penny on this product.
