For a little more background, at the start of the pool season the pool was green and filthy. The pool was uncovered last winter and had lots of leaves etc. in the water. My son first got in with waders, scooped, vacuumed, backwashed etc. multiple times then added lots of liquid chlorine. This process cleaned things up considerably. Eventually the water was clean but very cloudy and adding the chlorine did not improve things. That is when my son asked me for help. I thought we would start with the SLAM process and that is when we found the CYA was at zero. We added Trichlor pucks for a start to get some CYA in the pool because the liquid stabilizer would take almost a week to arrive. We then added two gallons of stabilizer which got the CYA to 40ppm and switched to only liquid chlorine. We then kept the FC chlorine level at between 16- 22 ppm for over a week and running the pump & filter 24/7. Using the OCLT method we determined the FC was dropping overnight so we still had junk in the pool. A few days ago we passed the OCLT test when the FC was unchanged overnight. We have allowed the FC to come down to a normal level for CYA of 40 ppm. We expected the water to clear but it has not (or maybe is starting to clear but is very minor if at all). It is difficult to tell. I'm starting to think this is just going to take a long time to clear the cloudy water. Does anyone think raising the FC to shock level will help or is it just going to take time with the FC at a normal level. Using DE may be a good choice as was suggested. Thanks.
Dave.
