PVC Black Pipe?

Plumbing supply stores. They will also have the correct solvent/glue for your application. Usually sold in 10' lengths. You can also get it at many hardware stores. A 10' piece is usually cheaper than a 3 ft' piece as you are not paying for the cutting (or "custom" sizing).

Thanks, I guess I'm going to plumb my 90gal with it rather than the white so it's not as noticeable. 1 1/2" from the tank and 3/4" back. Sound about right?
 
I just grab the schedule 40 white pipe and do my builds. If I need to change color I use the Krylon Fusion as it sticks to "plastic".
 
I guess I was thinking black just so it didn't show up as much as white would.
 
Well, I'd have to drill the back of the tank. It's not drilled so I'll have to be a ways form the wall and just wanted to keep it as invisable as possible. Now I need to find the Krylon Fusion paint.
