Take a look at my display below. With output set to 90%, the status bar (circled) only shows 1 bar. I can't remember if the bars increase with output; is this a normal display? Even at 100%, my SWG doesn't seem to keep up with demand like it did last summer when I installed it. Admittedly, I'm still tuning the water and haven't officially opened the pool.
FC - 5 (brought up from 0 with bleach)
TA - 50
Ph - 7.5
CYA - 40
I plan to add CYA to bring it up a bit (80). Wanted to run the SWG for a week of so and see where TA and Ph fall out after that.
