Does anyone know where to get food grade clear tube? I plan to bend a section to form a outlet similar to the do! aqua jet rather than a standard lily, even better if it had a clean join so flow direction can easily be changed. Does anyone know of anything readily available or where I can get the parts? I've looked at Loc Line which seems perfect and is what Tom Barr recommeded but it's chunky nature and my small tank size rule it out for me.
