Tank to Tank Water Bridge

CWO4gunner, if you're going to build one let me know what kind of design you're going to use. I'm already redesigning this one :-p I am thinking of reconstructing it with glass sides, but a plexiglass top that I can seal a valve directly into. This would also mean not using a completely flat top so that the air would reliably gather in one spot under the valve.
 
In your next effort consider having the top peaked like the roof of a house. This will allow you to control where airbubbles collect. Drill a 1/8" hole there and mount in an airline fitting. Connect fitting to the venturi inlet on a powerhead and voila! Automatic bubble eliminator. Works well on external overflow boxes as well.

Awesome! This is a real help for me because I will bridging my two 80's but just for the use of one filter (FX5). However since they will be next to one another I think I will just use a 2" clear hose arched with the fitting on top bend going to the power head as you say which since submerged should be safe even if the power head loses power air wont rush backward and stop the bridge, Important sine in my case water filling one tank and being pulled out of the other will flood without that bridge, unless I install an overflow switch to kill power to the filter.
 
Did you ever think to use clear pvc pipe? I i remember looking somewhere, you can get like 3 or 4in clear pvc pipe with all the appropriate fittings. then you can use the cement for welding Plexiglas to make sure it stays clear when gluing. Just a thought i had when i saw it and when you mentioned you wanted to make it simpler.

And if you think about it, you can make kind of a gerbil maze of sorts if you used PVC lol....

EDIT: Doh, i guess i skimmed past the part where you mentioned pipe.... BTW i looked at prices in hopes to build my own. they don't look pretty....

Anyway it can be done its a neat project. I was almost going to do it with my side by side twin 80's but when I realized I would have to maintain the same species and the amount of high GPH between the tanks since Id be using an FX5, the bridge would have been more like a vacuum transporter, involuntarily moving fish from one tank to the other LOL. I think the water bridge idea is excellent on a smaller scale, no more then two 20 gallon tanks with independent filters systems.

Exactly. Glass and a tube of silicon are so much cheaper. Just make sure your order of assembly is chosen in a way to make it easy.
 
I would think cleaning would be as easy as pointing a powerhead in one end and blowin the debris out the other.
