I want to build 2 biotowers above my 300g out of clear tubing I am having a problem locating it. I want to use 10" or 12" round. Anyone have any ideas?
An inexpensive way to do this is to make the cylinders yourself out of thin acrylic sheets. You can heat them and bend them into a cylinder shape, then glue and clamp the seam.
Even cheaper, plexiglas from a home improvement store. You don't have to heat it to bend either. Get some nylon screws with wingnuts and drill desired number of holes on the ends. Bolt together.
