So I did a 6 day SLAM before having to take my daughter to college. It passed all 3 criteria 2 days in a row before I left. I then switched on the SWG to 40% before leaving. On 8/19:
FC 19.0
CC. .5
CYA 60
Pool temp 84
Upon return I was happy see the water was still CC. BUT on 8/23
FC 27
CC 0
CYA 60
Turned off the SWG but as of today 8/27
FC 26
CC 0
CYA 70
This despite 3 good days of hard afternoon rain? I am in FL and it is very hot and very sunny. I would have thought the FC levels would drop more quickly with no source of ongoing chlorine but suppose the CYA is doing its job a bit too well. Wife is a bit impatient in not being able to swim. How long can I expect the FC levels to remain that high? At what level is it safe to throw her in?
BTW, 18K in ground plaster pool.
