Have you considered a shower filter for your skin reaction? Maybe it could purify the water more so that you won't get any more weird reactions?
Actually I forgot to mention it in the video but we do have a filter on our shower head. We've had it since we first moved in almost 3 years ago. It helps with the rust (before we got it my hair was turning green!) but not much else.
oh boo. :( well, at least your hair isn't green! ;)
