On another thread, I had asked about pH, and as the discussion went on, I was told to get my Cl up to 8. I got it up to 11.5, last weekend, and it has been steadily dropping over the last week. I performed a drop test last night and got 3.5, this morning it was 3.0
The other test results from my TF100 (if no user error was involved) were:
pH 7.8 - (it has been a day or two since I added acid, which I did this morning)
Looking at the chart for SWG, it looks like if I just raise my CYA to 60, my Cl may be OK. I am curious of why it dropped so quickly over the last week. I run my SWG 12 hours a day.
Is there anything to worry about?
