So since I've had bettas, I've been using the filtered drinking water they sell in the big machines (you know the ones where you bring your own water jugs and fill them up in those machines outsides of stores?)
Well, I've been looking around online and apparently.. That's not good to use? I'm really worried and also a little sad considering it's a lot easier than using water conditioner on tap water.. Though I've never had any problems with it.. I've had all of my bettas since early summer '10.
So: Is it safe to use filtered water on bettas?
