Hi all- working on building my greenhouse (12x24) and am preparing to begin my aquaponics obsession. i feel like i've read through every forum and wolfracer's build really spoke to me, so i am basing my build off of his (see attached picture). Per his recommendations, i will be increasing the feeder tube diameter to 2", raising the fish tank (the ibc), and adding a swirl filter.
My questions are-
1) is this a feasible setup using only a airlift pump (glenn martinez style) pumping the water from the sump to the fish tank? (everything else is gravity fed)
2) how would i integrate a duck weed grow bed? I have a spare blue barrel i could use (maybe cut lengthwise?)
My plan is to get the energy use low enough to use a solar powered air pump with a battery back up and have minimal mechanical upkeep. any further assistance is greatly appreciated- Thanks!
