SWG Intex pool in the shade - high FC

[Alexanders]

We have an intex 4500 galloon pool with 1200 gph sand filter and intex swg. Our pool is in the shade, basically always. We have a wooded backyard. I really think the shade affects or FC loss, which is very little. Lately it has been raining a LOT (midwest, MO). I have been running the filter 10 hours a day and SWG 7 hours a day. After a few days of rain (no swimming) and no testing, today I tested and my FC is very high:

FC: 11
CC: 0
CYA 75

I am using the TF 100 Pro. Pool math says up to 11 is ok with 75 cya. Is it ok to swim (assuming it stops raining)?
Should I run my swg for 6 hours (instead of 7)? (I was doing that before the rains and FC was running around 7 not as high likely because we were swimming?)
Any other suggestions?

With CYA 80 (we round up) it is safe to swim up to FC of 32.

Lack of suns UV rays with clouds, shade, or rain lowers the daily FC loss.

Yes, reduce your SWG runtime or %.

Adding on to what ajw22 said, if your pool gets little use, dial it down a bit. But if you get alot of bathers all the time, leave it where it is. Mine is normally around 10-13 with a CYA of about 70 but I always have huge bather loads so I try to leave it on the high side.

Remember that pH test is invalid when FC is over 10. So we usually don't recommend running FC over 10.

Ah yes, this is true. I control my ph with automatic co2 injection and rarely test for it as it is very stable at 7.5.
