saltwater generator
fc - 3.5
cc - 0.5
ph - 7.4
alkalinity - 120
cya less than 20 (dot was slightly visible at 20, but disappeared when tube was full).
1. will the combined chlorine go away with time or do i need to shock to get it to zero?
2. should i wait till combined chlorine gets to zero before raising cya?
