Im plumbing the overflow on my oceanic 75 gallon. Included with the bulkheads are two barb fittings that slide into the bulkhead(and I would assumed need to be glued). Im not to fond of the flexible tubing used with these fittings and I would rather use pvc. However I am building this tank so I can easily dissemble it if need be. I have looked at different threaded pvc fittings and quick disconnect style fittings but they are all to big to pull back through the holes drilled in the tank. Does any body have an idea on what I can use beside the flexible tubing?
