I have been in the process of converting spa to BBB the last 2 weeks and have had a couple of slips but I think I'm close.
Numbers taken today
FC 4
CC 0
PH 7.7
TA 60
CYA 100
Borates 50
First the obvious, my cya is to high. This happened when I was adding dichlor using old test strips. My T-2600 had run out of reagent. So I way over shot FC and CYA. This fix seems to be drain water and refill but how much? My spa is 510 gallons.
TA is low but when I raise it PH goes up so I add MA and TA and PH go down. I aerate to raise PH but then TA stays low?
Thanks for the help Jim
