A lot of people have been asking about simple DIY aquaponic system for balcony or small rooftop. Working with a group of kids from CYPA River, Fluffy, Christina, Pearl, and Nancy, we have designed and build a small system that with components easily source from Taobao and very little modification.

Place the grow bed on top of the tank.
Prepare a 30cm long and 5cm diameter PVC pipe with holes.
