I'm in the process of switching to SWCG as well. I have the plumbing done. I just now need to hook up the electrical and mount the panel...and add salt to my pool. I have a Taylor test kit and it reads 600ppm. So I've got 400# of salt in my truck to add.

It's not a cost savings. The salt cost alone is about a season's worth of chlorine. It's the convenience because I cannot test the water everyday.
