I'm looking to build a working "but small" model of my pelagic fish aquarium design. If anyone knows of a source of salvage cast acrylic tubing, I am looking for three pieces 24 or more inches long and at least 24" in diameter. 1/4 inch would be preferred but I can probably use as thin as 1/8. Thicker is not a problem, scratched, foggy, can be polished out with a little elbow grease and power tools both of which i have. Give me a heads up if you know of some, I have been looking locally and I can't find any so far. New the stuff is just astronomical in cost, at least to me.
