anyone piped their tank with Aryclic tubing or Clear PVC?

[Milad]

Im trying to find a way to pipe the return on my tank as aesthetically pleasing as possible. I have to bring 6 feet of pipe over the length of the tank and I really do not want to build a canopy for it. so.... I had a dream, a dream to use clear tubing and have it sit inside the top or just above the glass and run the length of the tank.

Has anyone ever done this? If so, is there a downside? could it get dirty inside?

The clear PVC is twice the cost of the Acrylic and but the problem is im not sure if I can glue the PVC to the Acrylic because they only make PVC elbows.
