Super-Simple Aquaponics

I have as one my goals making an aquaponic system.  I realized a while ago that I was going to cheat at this one anyway -- make a small aquaponic system to figure some stuff out (mostly getting to know what I don't know) and then if that went well enough, either make a bigger system, or even just buy a bigger one.

Well, it doesn't get any simpler than this:




If I wasn't working on my rental house to get it ready to sale I would probably manifest a version of this by the end of tomorrow. (For example, I saw some plastic milk jugs left as trash by a park I visited today. I would make the planters out of them. As it is, I just have a random bucket of water serving as a potential bird bath.
