Yeah I had this thread bookmarked also, like form the original date posted. This is my version, and how it is now.
This tank is 48" wide, and currently is using a temporary 36" light, a single old T5 bulb for the light source. The goal is to use a 49" long T5 bulb.
With it on:
With it off for comparison:
Construction:
So I was able to do the other thing I was really waiting to do for a lonnnnnnnnnnnnnnggggggggg time!! a "lit" background
Even though the lit back is brighter in pics below, its becasue of my photog skillz. It looks more like the pic above, but its a little smoother transition than that with the eye. Well see how it looks with main lights on soon!!
Basically a "blue translucent" sheet of acrilic, with a light behind it, well more like a lightbox..
3" lightbox with back reflective cover removed
See the light at the top
when tank was not complete yet:
All skinned, buckled up, and done...with main tank lights on (still with temp 36" light):
