So few details have been provided about how it works (whatever "it" is) that I must view this system as I do other alleged miracles. What are the inputs? How does this improve on planting a garden? Most aquaponics schemes require an input of commercial fish food, which is fine but equivalent to an input of commercial fertilizer, so is unlikely to fit into a highly sustainable paradigm.
