Not yet, though I have thought about snaking some through the PVC for a cool effect.
I would like to have nightlights, as I think they make the tank look nice, but honestly I have been so busy with moving into our new place when I built the PVC stand I just wanted it to be done and functional.. thinking it would only be there a few months.
Nine months later it's still there
No problem man, I'm glad to hear it helped.
Congrats on getting it complete, and would love to see some photos when you get the chance. The endcaps sound like a great idea to make it a more finished look.
