Yes, thanks for the responses from me too. I got a SWG last year (switched from Baquacil) and I love it. I came across one site where a guy lambasts salt systems and especially their effect on heaters:

I've not read about problems like he's talking about, but I'm not in the business. Has anyone here had problems with their heater due to their SWG?

I would think improper PH, etc. would be more destructive on a heater than salt, but again I'm no expert.
