i am looking into a small aquaponics system 10-15'x20-30' long, but i'm finding a very hard time about information and details about this for a small scale-small landowner just looking into options for a family, not large scale production types. i found only a few books which were very pricey, but i decided to buy one ($60.00). i was wondering if anyone has a similar system or can point me in the right direction (other than buying more books), so i don't blow my families savings for a wasted cause. times are difficult for us (wife and 4 kids) working on low payscales so i need to be frugal(?) with any investments i make for us but hard, manual labor is not a problem at all. thank you for any imput you have.
