AquaRite - Low Chlorine Output

[SJohnson]

Hi everyone . . . newly installed aquarite unit on a 18k new gunite/quartz pool, filled a week ago. My chlorine levels don't seem to want to go above 1.5-2 ppm, with output of cell set to 45%, up from 35% with no noticable difference. Just wanted to run this by everyone to see if there is something I'm missing . . . everything seems to be fine, so this may not even be a problem. Here are my test #'s::

pH - 7.4 (It's a battle keeping this in range, 2 quarts a day on average, new plaster/SWG is responsible, I'm assuming ...)
FC - 2 ppm
CC - 0 ppm (this is what makes me think that everything is working fine ...)
TA - 90-100
CH - 290
CYA - 60 and probably rising ...
Salt - 3000-3100 (would bumping this up help?)

Thanks!!
