A buddy here at work has SWG. Says nothing but good things about it.

When I talked to 1 out of the 2 contractors they said if I was to put SWG they will not warrenty the life time of the pool b/c it eats the plasture and that if I was to do limerock edgeing that the salt from it can cause to splash on the rock (where its dry/edge) that it will eat it up.

The other builder says that the chlorine pools is cheaper then SWG and would ONLY recommend SWG if anyone in my family has allergic reaction to chlorine.

Any takers? Myth?
