rain water ???

[Giant Val]

I use mostly rainwater in my fish tank. Where I live I don't have town water supply, so get most of my water from rainwater tanks. I do have a bore which I use to top up tanks if it doesn't rain, but this is not usual. I do 50% water change in my tank most weeks with pure rainwater. Fish are generally healthy and happy.
