Got a 10-gallon aquarium laying around in the basement or garage? The detritus of a failed attempt at adding tropical fish to the home decor? Austin, Texas college sophomore Jack Ikard found one in the back shed a year and a half ago, and decided to see if he couldn’t turn it into an indoor aquaponics system. After lots of tinkering, much of it at laser cutting co-op MakeATX, Jack came up with a prototype, and began showing it off at local food co-ops, farmers markets, and even last Fall’s SXSW Eco.
