This morning I tested FC/CC levels since the pool temp is just a hair above when the salt cell will turn off and I was going to see what bleach levels I need to add.
FC tested at 7.5, so that's fine.
CC tested at 0.5, which alarmed me, since I never have a CC other than 0 and the pool water temp is 51 so what could possibly be growing anyhow?
My theory is that the storms last night, light rain and lots and lots and lots of wind (did I mention stuff was blown over all over the patio), that there's stuff on the surface that the FC is taking care of, thus creating some CC.
Does that sound right?
If not, what does the collective think is happening?
Can't imagine anything is growing in there??
