You can order clear PVC from US Plastics. I think their address and
phone are in the back of the reefkeeper's FAQ. It is much more
expensive than regular PVC, and they probably do not have sizes as
large as for regular pipe.
4" clear PVC would be extremely pricey or not available, I would
guess, but their catalog is free so you might as well check.
The Aquaria archive is located in the /pub/aquaria
directory at ftp.cco.caltech.edu

I believe an overflow box is not necessary nor desirable in a planted aquarium.
Overflows such as the one in all-glass aquariums don't seem appropriate either,
due to the amount of water splashing they create. Since you are starting from
scratch, why don't just drill a hole in the back panel, just below water level,
and fit it with an elbow pointing upright ? Fit the elbow end with some sort
of strainer and that's it. No syphon to start, no cumbersome equipment to
clean inside the tank. You can even add a few more simple plumbing parts to
provide such things as additional security against clogging, and a simultaneous
underwater intake. To make it less conspicuous, use transparent PVC parts
(such as in http://www.savko.com/).

No, I know the difference between ABS and PVC. ;)
This is black Schedule 40. It is stamped on the side.
I saw 4" and 2" sizes, with some slotted 4" to boot.
Maybe it's only available around here--many houses are
built on pilings to survive storm surge, and exposed,
white PVC plumbing looks awful on a half-a-million
vacation dream home.
I was in the planning stages of building a waterfall
for the pond, and needed something to carry the water
from the filter outfall to the waterfall's basin. I
ended up using grey polybutylene because it was
flexible and would have less friction head.
