Yeah, I went and looked some things up right now. I agree, a lot of what came up seems to link water quality and poor maintenance rather than the fogger itself. I clean mine out every week and use bottled water (which, if the label is reliable at all, is demineralized).
That's a great idea. I might just start a mini-viv project when I find some free time. I've seen the vast amount of info and guides on bioactive setups, and some of them are really remarkable with the way they think of solutions to stuff. For now, I think I'll keep her on paper towels, but your substrate recipe would sure come in handy for when I get deep into making the bioactive viv!
Again, all your help is very much appreciated. It's a constant learning process when it comes to keeping a BP for the first time, haha.
