Thanks,
I received a few questions about the tank and I'll try to answer them.
The airlift is based off this design
http://www.malawicichlidhomepage.com/aquainfo/air_lift.html
My airlift is just a very very small version of that design using rigid ID tubing and plastic airline tee's. Basically a Lee's aquarium plastic airline tee is on its side so that the bottom of the T is pointing to the left. The top is used to feed the output line which is made of rigid plastic airline tubing that is bent at the top to direct the flow out to the right. The bottom of the T is used to feed in the air to create the bubbles that will move the water out of the lift. That is fed by another rigid airline tube which comes out of the top of the unit as seen in the picture with carbon.
The tank is currently lit by an Azoo Galaxy light which is a 13w clip on PC fixture. I'm using a standard 50/50 bulb. I do plan on replacing the galaxy light with a nice 13w desk lamp which adjustable arm - I just haven't had time to find one I like.
The air exchange is done via small gaps in the hole I drilled for the rigid airline and also via two small breather holes at either end of the lid.
As for corals, they need to be extra small and not require a ton of flow. The tank is super narrow - to give you an idea of how narrow I'll try and take more pics today.
The airpump that is used to power the lift is just an old tetra airpump I had - I placed an air flow adjuster on it so I can tune the flow of the airlift. Too much air and the airlift will just bubble, too little and not enough flow will be generated.
Hope I answered them all.
