So I started SLAMing my pool on Tuesday. I have a 23000 gallon vinyl chorine pool. Kept FC at 16 and it would go down every couple hours to 12 and I would raise it back up using the pool calculator.
Last night I brought the FC to 16 and this morning when I measured FC was at 22. It's currently 85 and sunny and its been 6 hours since this mornings measurement. I measured again and it was still at 22.
Can anyone help me understand why the chlorine is not going down? Pool still a light blue, can't see the bottom.
CYA - 30
TA - 50
FC - 22
CC - 1.5
what am I missing here? I am planning on getting the CYA to 40-50 and TA to 90-100. But it concerns me that FC is not dropping with all this sun and cloudiness in the pool.
