Okay, okay, I get it! LOL. Maybe you're right on your theory. As for water hardness, even if you fixed it in this tank, I'm guessing you use tap water in what ever tanks they're going to go in, so they're going to have to get used to it, eventually. I was going to suggest that you might want to mix rainwater in with your tapwater if you live away from a big city, but that gets way more difficult with bigger volumes, and would be impossible in the 1000 gallons the RTC is going to eventually need. So, I would agree, and say they're stuck with it.
