Hi Janet, just wanted to let you know how things are going. I ended up draining about half the pool...although it was clearer, it was still very cloudy and still could see more than half way down on a 4 foot deep pool. I then decided to go with the Flocculant, didn't have much of a choice really. I now have an almost crystal clear pool. Still have a little more work to do, but I am headed in the right direction. Thanks again for all your help!!
