Doing joeys led light strip with PVC and drain gutter, my problem is the PVC started to get heated and the PVC started to bow down(bend). Wondering how I can prevent this bowing of the PVC to happen. I had a drain gutter, spray painted the outside, reflective tape on inside, mounted PVC pipe to the drain inside, wrapped the led light strip to the PVC. The PVC ended up bending. Any other ideas how to fix my led light strip onto my tank? Can I use something other than PVC to prevent the bending?
