posting first here...b/c it says so. :) looking for some help w/ our Coleman pool

Hi,
My name is Melissa...I'm looking for some help with our Coleman 22'x52" pool. We bought it last year and all the metal parts rusted over the three month season. They've been replaced. Before this pool, we had an intex ultra frame, 16x48, I believe..we upgraded after the frame was bent soon after set up when a strong storm came through before there was enough water in it to hold 'er down. I have used a salt water generator for several years and am a huge fan of the ease of use. I haven't had an issue with rust before last year. I am just getting our pool going this year...my husband dutifully purchased the salt...and I am wavering between using the salt water generator or going a more traditional route. Is there a way to protect out pool from rusting while using our SWG? Thanks so much for your help!!!!
