I have a bunch of rigid acrylic Tube in diameters up to 3" ID, and as
small as 1/8" ID. All of it is over 6 feet long, is there anything I can
make out of it? Maybe some kind of fluidized bed filter? Preferably i
would like it to be useful to my planted tank.
Thanx,

How about a fish raceway? A tube (filled with water) which comes up out
of the tank and then back in (or into another tank). Depending on the
amount of pipes and your ability to weld them together, you could have
your fish tour your room along the walls or along the ceiling ;~).

It's already been done before, however if going from tank to tank, they
should be at the same water surface height ;~).
