Started with some PVC. After I had it cut and done a member of my local suggested plastic gutter :? which probably would've worked better, but for now I'm going to try this. Here's the parts:
Cut everything in half
I wanted a quick return and couldnt find a bend that would work so I made my own.
Glued together and wet test. No leaks
Got it running today, but still not in its permanant place, and need more lighting. The light there is lighting a 10g tank in my sump with chaeto, but with enough spillover for a portion of the scrubber. Spillover from the display should help light the rest.
