[video=youtube;exR8NE7hmeY]http://www.youtube.com/watch?v=exR8NE7hmeY[/video] I was watching this video, and I was like oh my gee willikers oh I do declare something like that might be awful helpful in cleaning debris from my aquarium without doing a water change! Concept seems simple enough, create a vacuum by trapping the air in a tube like apparatus, then release the air and let the change in pressure create suction like when playing with a straw in a restaurant. question is letting the water escape without letting the soot escape like with the debris filter. I could see a couple ways to do this but do you guys have any experience with building something like this? I was thinking maybe just try to replicate the design but any improvement ideas on this would be very helpful, thank you!
