This is probably not what you are looking for but here is my setup.
I have since taken the old PH out and put in a minijet. I added more LR and the power filter has sand, rubble and cheato on the filter compartment. The lights are a DIY PC with 2x32 50/50 bulbs.
The key is shallow for effective lighting. Here is a prop I recently built for someone. 110 Gallons, 3'X4'X12" I have recently added a large overflow and I'll try to get him to send me a pic of it running. He has a single 400W HQI pendant over the center about 3' above.
