Bad for plants? I was just wondering. In all my successful tanks I have used rain water. In all my less successful tanks I have used "softened" tap water. I know it isn't properly softened as in lower GH, so is it possible that the Sodium or whatever those salt tablets are can be harmful to plants? I'm probably just trying to find a scapegoat for my recent efforts, but if anyone remembers my 40cm layouts I didn't have any issues with them. It was only when I started on tapwater that I had issues. If it is possible it's having some effect, I'm gonna start using rainwater again.
