My comment was not meant to stop you from using distilled water entirely. You are only going to be there at most, what, three months?
I was thinking of the water at home, for you and all the family. If you like I will dig up how to built a filter that provides you with clean water - but with the needed minerals.
Glad to see you are looking after yourself.
My computer died on me (blue screen) so I need to get back to finding a solution...we'll chat soon
Oh, when you you start your filming (solar farm)?
