I started researching Aquaponics in 1995 and I have been building systems since 1999.  At one point I had about 1,500 gallons of heated pools (heat pump) w/Nile tilapia. I grew hot and sweet peppers, tomatoes, cukes, herbs, etc... in a combination of gutters and  grow beds w/hydroton - I canned a lot of tomato sauces and chilli sauce.

One I put together in my dining room which had lots of east and south facing window. It included a 55 gal tank w/Red Belly Pacu and a 100 gal. Rubbermaid water tank (tucked into the corner between windows and included a water fall) w/smaller Nile tilapia.  The 55 gal fed three 10' pipes with net cup holes cut every 6" while the 100 gal fed a matching unit in the south window and a "tree" I designed which had one "foot" in the end of the tank for drain back. The "tree" also had aeration provided through mini soaker hose.  It worked well until the company I was working for went under and I lost the house.  Too much yard shade anyway.

I loved the Nile tilapia for the way they changed colors, you knew when they were going to mate,  and took care of the young. 

 And I always got a kick out the reaction I got when people asked if I like to fish and I replied that yes, I thought it was fun to go out to the garage, grab my net and get fish out of the pool for dinner, and then show them. That always led to a couple of hours of interaction.

At this time I don't have a system set up but I have moved into a place that will allow for it once I have completed the remodel and have time to put into it's planning and the funds.

When the remodel is finished and I can move my things out of storage I will try to find my photos of the previous systems.
