I have been in the opening/shocking process for about a week and a half now. On June 1st these were my test results:
CA 20 (30 when I started, had lots of rain and had to lower the water level in the pool)
I have had trouble with what I believe to be calcium scale this year. I was advised to drop my PH down to 7.0 and keep it there for several weeks to help the scale work loose.
With a CA of 20 my shock level is 10 so I have been shooting for 12 just to be safe. This morning my FC was 13.5 and now, at 4:44 it is 6.5. I happened to think that my PH readings are not necessarily accurate with my FC so high and that maybe I should have left it alone until I was done shocking?
My last test with my FC at 6.5 shows my PH at 7.0. My water was clearer a few days ago then it is now. It has turned more cloudy. As I mentioned I have had trouble with scaling on the walls. My husband spent 2 hours scrubbing the walls to help work the stuff loose (it was cloudy before he did this). I am going to vacuum the pool floor in a little bit, as much of it has settled to the bottom. Do I need to make an adjustment to my PH and CA again? We are leaving for a week long trip on Friday and I was really hoping to have this pool cleared up for the kids before we leave.
