Yes - some of the contents came from my 46 bow front that is no longer up.
Most of it was in tubs in the garage curing prior to start up -
The black background was suggested on my previous tank after someone saw a photo of it with a blue background. I actually painted this one - no water behind background this way. The black brings out the colors and shows of my fish better.
Cost? I bartered - traded - fragged - borrowed - and scavenged most of what you see.
Not where I want it to be yet - but getting closer to the goal.
