So I did the OCLT test last night. Went from 24.5ppm to 22ppm over 10 hours. I'm assuming I haven't passed the OCLT test? Or is my FC too high and need to bring it further down to get an accurate OCLT?

I won't be home till tomorrow morning at 7am. It's overcast and raining 3-5mm here today (Toronto). My SWCG is off and pump is running 24/7. Any thoughts as to what should I expect the FC loss to be tomorrow morning? I was using the pool math app to determine chlorine needs during slam and...

I'm trying to determine if my SLAM is done. Water has been crystal clear for 3 days at 31ppm with 80 CYA. Did the OCLT last night. Test at 10pm was 31ppm and this morning at 6am it was 29ppm. Is it normal to lose 2ppm with such a high chlorine saturation (31) or do I need to keep SLAMming...

Ok thanks. One more question- is there any way to use a 5ml sample of water instead of 10ml as I'm going through my drops fast when testing for 31ppm. Thx

Is it OK to have the SWCG running during a SLAM? I just started a SLAM as my pool water was getting cloudy. CYA is 80. I brought it up to 31ppm using 15L of chlorine.
