We're about to revamp our entire garden idea. After two years of running an aquaponics system and getting next to nothing out of it it's time to put it back on the ground. Our primary pump died last night and poured 500 gallons of water out of the DWC onto the ground. Our choice now is wait two-three days for the new pump to arrive or just tear it apart and make four raised beds out of the media beds and DWC that we already have built. I could make a monster bed out of the 8x10x32" in ground pond that we have but then I'd have to find a home for all the fish and the water plants my wife loves so much.
Anyway we're headed towards ground gardening again. Hope we get something out of it.
