I understand about using certain materials to keep costs down, but look at the design, craftmenship, and overall quality of materials of this tank. And then they use a plastic tube to hold the most vital part of a tank -- the juice. Unbelievable!
Yeah, it's clear so that makes it pretty, and it's probably easier to mold and work with, but clear plastic limits the juices you could put in this tank. Polypropylene admittingly would cheapen the look of this tank, although functionally it would be better than the other plastic. Pyrex is the ONLY tube material worthy for this tank.
+100. I concur 100%
