You need to keep your chlorine level up until your salt water generator kicks in. Everything else you've been told is right on target.

With an SWCG, our experts tell us you'll be looking to have a fairly low T/A, 60-80 ppm,
a fairly high CYA, also 60 to 80, and
to keep your chlorine level at least at 1/20 of your CYA level. So if CYA is 60-80, free chlorine should be 3 to 4 ppm.
