can I let FC drop?

[engrav]

good evening
pool not closed and water is getting coooold
water looks fine
CYA is 30-40 and PoolMath FC range is 3-7
can I now run at the low end of the FC range?
thank you

You can always run at the lower end of the range, just make sure it never drops below minimum and keep steady with your testing despite likely lower chlorine demand.
