I just did my OFCLT and it looks like I need to slam. My water is crystal clear, but I noticed a couple of Algae spots and also that my FC numbers seemed to be a little lower than they should. At first I thought my CYA was off and I was losing the FC to sunlight. The CYA was off, so I corrected that, but still no real change in the FC. In any case here I am.
My FC test last night was 5.5, and this morning it was 4. CC=0; Ph=7.5; and CYA=70.
I have two questions, do I leave my SWG turned on while slamming, and can the kids swim during the slam (this likely won't be too much of a problem since we're due to get rain tonight through Monday)?
