I've been running an Aquarite SWG in our 26K gallon pool since early March. The water has never been anything but crystal clear. I run about 40 PPM CYA. The SWG is set at 40% running for 12 hours each night. When I took a water test yesterday there was zero CC (or so litttle it could not be measured with my Taylor 2006 kit) and FC was about 4 PPM .

The only chemical maint. I do is to add about a quart of acid once a week to keep PH in check.

I do have a poolskim that keeps the surface of the water clean and a pool rover than maintains the bottom. I usually run the rover a couple of times a week.
