Owen did you ever look into prill beads?

I learned this from Andreas. I used it for several years. It is simple and cheap.
I have to buy another glass jar to start it again. We were away for several months and I did not want the water to sit around. It is about $20 for the beads, it makes the water "thinner", and it lasts for years. I have them also in the toilet tanks.
You can read about it on this website http://www.thewolfeclinic.com/prillbeads.html
