>>1367266If you are interested in aquaponics, I will recommend that you look into "quackaponics". You essentially collect substrate from a duck pond rather than a fish tank and you don't have to worry about fish dying in case of a power outage. You can also collect duck meat and eggs from this system. There are a few different ways to implement this, the one in pic related is just one method. The substrate can fed into a plant bed as well.
