Scott has been running this system in his backyard in NE DC for over two years. Below is the fishtank, a submerged IBC Tote with cover. Scott estimates he has about 10 Bullhead Catfish and over 50 Blue Gill, some of which have been here almost three years! He and his family have eaten about 15 of their own fish grown in their own DC backyard… Gnarly! (He says the Blue Gill are much tastier.)
Up top is the grow bed. Scott estimates that during the warmer months it produces about a salad a day for his family. Wow, great numbers. And he uses rainwater from his roof, very environmentally friendly! (and lower pH)
As pictured, the system is operating under the tarp for winter. It expands out during the rest of the year, and Scott is continually adding growbeds.
