      So we had a very hard rail and I purchase 2 bottles of this stull which really is overkill as one bottle should have corrected the issue. Pure junk. This did not do a single thing for our pool. Still cloudy as ever, clean but cloudy. I have used this stuff in the past and has worked perfectly. This was my firm time going through Amazon for it and I don't know if it expired or what the problems but the stuff is not cheap and this last round produced 0% fix for our pool.

      I have used this product many times and have been happy with the results. It is very concentrated and last quite a long time. It is the same product I can buy at the big box retailers but Overstock has a better price and it is much easier than a trip to the store , which is often out of stock.
