When is FC too high to swim in?

[stevet1]

I left town for about 5 days, and forgot to disable the ORP sensor in my Autopilot TC. When I got back my FC is now about 14.

Here are my #'s
ph 7.7-7.8
FC 14
CC 0
TA 80
CH 420
CYA 70
Salt 3200
borates (est 40-45)


So when is FC too high to swim in?
Also, I notice that when I disable ORP on my Autopilot TC and set the SWG to a %output, the % seems to vary by itself, and sometimes even goes down to 1%. Is it because of the varying water temperature?

Given your CYA level, that isn't all that high of an effective chlorine level. You should be fine swimming in that.

The AutoPilot units are temperature compensated, which means that they change the percentage on their own based on the water temperature.
