I was somewhat thinking the same thing about FC usage until I read this "the rule of thumb is, you'll use approximately 7 ppm FC per person per hour in a 350 gal tub. "
I use my tub nightly, for about half hour to an hour each time... so basically my SWG operating 8 hours a day can basically not even, or barely keep up with a single bather load nightly...
So its not surprising that you have to add a lot of chlorine.
