Well, I was asked by my kid's 4H club to help them do an exhibit on aquaponics. So I am drafting some new plans for a small demo system, and I'll have the kids make posters with information about aquaponics. A friend of mine (Allison) shared with me a picture of a small start up system, and I'm thinking of doing something on this order.
I like that it is see-thru, and people can see the fish, the grow media, etc. and it's not too big of a system, for the purpose of being a demo. I think I'm gonna try it with some goldfish, and grow some lettuce, and maybe beans for the demo. Already ordered a small pump, a freshwater tester kit, and a timer. I can use some of the grow media that I was planning to use with my bigger system (perilite). Then what I need to do is build the plumbing and a bell siphon. So I'm getting jazzed. But a little nervous too, as I haven't actually started up my bigger system (55 gallons). Mostly nervous about the bell siphon and getting it to work.
