Sandi, thanks for the article. We're going to Georgetown in a couple of weeks to look at a setup there they will have open to the public for some type of aquaponics week to coincide with Earth Day.
Jonna, thanks for the response. Australia does seem to be ahead of the curve on this. I don't want to harvest fish either, and from what I've been told the Tilapia like warm water, so they would be a summer/fall fish in my open pond. My setup is just a back yard hobby.
