Hydro/Aquaponics

I want to setup a very small indoor system to get a feel for this. I'd like to see how much plant matter I can grow from that. Probably just basil and oregano.

???

• How many gallons per sqft of growing space?
• What grow medium

Components

• Fish tank : I have the old 10 gallon fish tank.
• Pump
• Beds
• bell siphon
• auto feeder (for fish)
• Lights : I'd like to use LEDs because that's what I'll want to use in the long run.
• Timers
