CYA at 40 will be fine. You will still want to add chlorine every day, though at 40 it won't go all the way to zero in two days.

FC: 7.5
CC: .5
TC: 8.0
CYA: 45
CH: 150 (I added some balance today to raise this)
TA: 160 (i ran the spa for a while today to lower this)
ph: 7.2
As i said, i feel better about the #'s- thanks to the advice of everyone.
A couple of questions:
1- i have read that i should add some chlorine each day; how much should I add daily?
2- do i need to run the spa for hours to lower the TA?
