I'm relieved to find an online community to bounce some ideas off of. I have been thinking about aquaponics since I discovered it a year ago on a PBS special. I took notes and started searching for simple design parameters. Such as how many fish will one person eat in a year. I know there is an answer out there but really its subjective to the person. I eat fish maybe every other week so thats maybe 23lbs of fish I'd eat in a year. Anyway, I went out to Olomana Gardens in Waimanalo, Oahu for a tour and have been thinking about designing and building a small home system ever since. Here is what I have come up with so far;
3 - 8X2 ft growing beds 12 inches deep (lava rock growing medium)
1 - 250 gallon fish tank
up to 48 lbs of fish at any one time.
Here's the twist - 3 - 8X2 ft rabbit cages under the growing beds.
And another twist - Make the fish tank look like a pond by burying most of it and have the return lines from the growing beds cascade as a water fall.
The rest of ideas that I want to incorporate are;
3X bell syphons for the flood/drain growing beds.
maybe a smaller pond up higher for duck weed and breeding the replacement talapia.
Any helpful ideas are welcome.
