We have had a pool for 3 years now and I have been following you site from the beginning. This was the first year that we left the pool up and we had a slight problem , the cover came off and went into the pool. So this was my first time "opening up" a pool and having to recover from a issue. I followed the shock procedure in pool school and had our pool ready to go in less than a week. The pictures really are amazing when I go back and look at them.
