OK, as much as I am sick of this thread I figured this was the best place to post an update that would reach everyone interested.
The wave height is adjustable- you can lower the power of the driver.
Using a branch adapter you can connect as many as four waveboxes for tanks up to 1200 gals. Someone asked me a while back about a 1000 gallon tank and I didn't have an answer.
The new outlet screen is finished and it is pretty neat looking, it looks almost like a landing net section but of a harder plastic. Being so thin the sections do not impede the flow too much.
The manual says it will work on any aquarium over 27.5" long.
I just finished proofreading the manual, that is how I have this info, once I get the revised version i'll let you guys take a look.
