      I was pleasantly surprised by how well this shock treatment worked. As soon as I poured it into the deep end of the pool, it went to work. Within what seemed like minutes, I had a sanitized pool. However, since it is so powerful, it required a flocculant/clarifier then a drain-to-waste vacuuming. I learned a little goes a long way for weekly maintenance.

      This shock is stronger than HTH and works better than the other more popular product , but since it is just chemicals who needs to pay for a brand name. I used this on my in ground pool and have been very happy. it's also good not to have to hope the local store has enough product in stock. oh and did I mention it is cheaper than any other I have found. I compared the prices at several online sellers and this was the best one.
