3 weeks into new fill in 600 gal spa
been lowering ph every couple days to maintain approx 7.5
TA was 80, then 50, 40, 30, now it's only 20
ph is currently 7.3
is this bad?
Am thinking about auto-chlorinate system to lessen daily FC checks.
Is SWC currently the favorite for use with spas?
I have a 650 gal system with ozonator.
It gets maybe 4 person/hours usage per week (in winter), 1/2 that or less in summer.
