After restarting my SLAM last Thursday due to some issues at first, I am now really starting to see results. Chlorine is holding fairly steady, the "chlorine smell" is gone, the water is cloudy but blue, and I can see the bottom, barely, but still a huge improvement!!! This site is great, I wish I found it 8 years ago! Thanks to all for the great info here...it is truly a must read for any pool owner!
