I'm slamming with high numbers to make sure any algae is gone before closing up for the winter.
My CYA is super high, 140, but draining weeks prior to closing wasn't optimal so I chose to heighten FC.
I was able to keep it in the 40s all week and started to SLAM yesterday pm. Easily got to 55 around 7pm and was still there at 9:45pm.
Woke up this am around 9am and still at 55. CC has been steadily 1 or less (using 5ml samples because of high FC target).
So the OCLT looks good. CC pretty good. But I'm still cloudy (though no green anymore!). I can see the bottom fine, just not crystal clear.
I have the ability to test many times this weekend to keep it at 55 if necessary. But is it? Since I have a sand filter cloudiness make take some time, right? But does that prolong the SLAM numbers?
I'm fine with either answer, just don't want to waste chlorine/reagents if it's not necessary.
