27" round, AGP, 2nd full summer. I put in a SWG 3 weeks and noticed on my stainless steel service panel, very small rust spots, all over it. They look like rusty blemishes, very much surface rust at this point. After watching it for a week, they are getting bigger. I am afraid that in another 6 weeks, the entire panel will be rusted. I have no other rust issues; screws on my steps, or on the decking. Is the salt responsible for this? All chemicals are where they need to be. Salt is 3500ppm. I do need to do some bonding work as I have not bonded the SWG or the pump while the pool and heater are bonded together. Any ideas??
