Anyone out there have any extra acrylic tube? I want to make a small air powered skimmer similar to a MAME DESIGNs unit. US Plastics has everything under the sun for this, but I have to buy 6 feet of this, I really only need about a foot at max. So I figured I would toss this out there to see if anyone had some excess acrylic around. I have some 4 inch diameter, just too big for my little tank.
