my tank backs up to my garage wall so I actually made an access door in my garage wall to get to the plumbing. I have two XR 15's and I bought two cheap tv mounts on amazon because the rms mounts IMO aren't worth the money and I didn't want anything on the tank.yea still figuring how to modify the plumbing a little to get it closer to the wall. I knew I would have to do that so no big deal... all the fittings are DN20/DIN 25 (3/4) - but Chinese and a bit hard to find.
How did you mount your lights? I was going to get some aluminum extrusion from Alliexpress and build my own coming up over the back, but then the drain lines are in the way to support properly and materials along save very little vs the HMS mount. Considering HMS mount bar instead now.
