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.
Much more cost effective than buying these individually and the convenience of having a summers worth delivered to the house all at once was well worth it. I loved that I spent the summer in the pool and not the pool supply store.
Works like a charm! For the first year we haven't had to constantly balance/test our pool. The chlorine levels maintained and the water stayed beautifully clear.
