I have a 25K inground vinyl lined pool. Opened it a few weeks ago and after seemingly getting it balanced (had to add algecide, Alk up, Stabalizer up and Calcium Hardness up) it seemed to be ok but then after shocking it with 2# shock 4 days ago, the FC is at 10 and the TC is at 4 and aren't moveing down any each day. Also, my Stabalizer is showing maxed out. Do I need to drain some water and add fresh to try and dilute the high levels? Thanks.
