With CYA at 50, it'll be safe to swim once FC dips below 19.8Hello Everyone,
So, last night I went to bed with ... FC=21 This morning I tested ... FC=19.5
I have a couple of questions regarding once I pass the OCLT test:
1) When is it safe to swim? (Please keep in mind I have little grandkids that swim a lot)
2) Once I pass the OCLT and FC is allowed to drift down to normal levels, what am I watching for?
Thank you very much.
