I'm using this to "learn the ropes" of aquaponics. For those who aren't familiar, aquaponics is a combination of hydroponics and aquaculture. My goal is to create a system that takes as little of my time as possible, and provides me with some food. I designed the system to use cheap 5 gallon buckets for the tanks/growbeds.
