I talked to Steven at Polly's some time ago about the Thrive kiosk. He said they've inquired about it and are on a waiting list. That would be amazing though. Take your water in, put it in a machine, get accurate results and have it push the results to the web.

I was reading not long ago about a German company that you mail your water to over the course of a few months and they send you a "recipe" to dose your tank with. I thought it was a neat idea and I think it's what Thrive is trying to do.
