Admin note:
Turns out this spammer is associated with the cheap pool products DOT com and over night pools DOT com domains, and spams to promote those sites. You might want to keep that in mind, before purchasing from those domains!
I'm not sure about the compatibility thing you are referring to but as far as I know adding excessive salt or over-salting will not create any damaging effect to your chlorine generating system but will make your pool water taste salty. In short, your pool can turn into a miniature sea and some swimmers wouldn't mind this.
However if salt level reaches beyond 6000 ppm then corrosion damage can occur to metallic equipment such as stainless steel and the next thin you'll know is you have to replace your handrails, ladders, light rings, skimmer fittings et al. Reducing the salt level can be done by draining some water and refill with fresh water - technically termed as dilution.
Hope this helps.
