I am planning on doing the overnight chlorine loss test tonight...couple questions.
Background: I opened the pool six days ago. Water is clear. FC is holding ok but not great (I'm raising CYA now to help with that). I'm not SLAMing anymore now, but I want to make sure there are no problems, i.e. algae hiding anywhere and using up the FC.
I know I need to turn off the SWG tonight. Do I have to leave the pump running for the OCLT, or is it ok to turn to the pump off tonight? I've been running the pump continuously since opening to clear the water. I really want to switch to timer mode and only run it 8/9 hours during the day.
Is OCLT better/more reliable with higher FC levels? Right now I'm at 3 FC but I could add some bleach to raise it up before tonight.
CYA was 15, raising to 30-40 now
