I'm interested in this project... any progress?

Another interesting DIY on this topic is at http://angel-strike.com/aquarium/CirculationSystem.html

I've seen another of somewhat similar design but can't find the URL right now...

Not yet. There are so many things that I need to do first in order to get onto the next step. Thanks for the link, I love checking out different ideas and DIY stuff.
