Mr. Carroll Bryant looks at his backyard aquaponic system “The Knight” in its second growing season. (It’s named after the Ballou H.S. Knights, across the street.)
The Knight has a 50 gallon inground pond currently with about 15 small goldfish, and one medium size (5-inch) comet goldfish. We covered the pond with weed cloth to prevent excessive algae growth.
Water is pumped up to a 10 gallon grow-bed filled with hydroton clay-media. A bell-siphon returns the water to the pond.
Right now Carrol and his wife Janet are growing green onions and some bok choy. We’ll have to get some more fish weight to really ramp up the growth!
