It's 3 - 2 x 4's on top with a brace from floor to ends of those 3 . Each tank is sitting on metal trays on the boards. Then plastic covers over those. The cabinet is solid double thick walls of cross cut oak. All inside areas have been blocked with wood supports. It's much more solid than the dedicated fish cabinet I originally purchased for the set up. I don't worry about this particular antique because after we purchased it we found the person had significantly made changes to it when refinishing. That killed it's value. Right now I'm just letting it sit as I decide whether to plow on or get that fish cabinet out of the back room. Nice I'm getting such great advice. I'm in no hurry. It is all in the planning. Rethink, replan,redo. Thank you! K

Still working to finish shoring up far ends. Center and legs all supported straight up the middle. I think I got tanks and substrate all about the same heights. Once all is well supported inside and out, then add plants, etc. Let it cycle etc. Do you think it looks okay to continue with fish bridge. I'm thinking I'm just going to use the elbows and sleeves for a short but sweet bridge.

I really appreciate all over your comments. Very useful for planning. I've thought about honey gourami. So definitely no aptisto for my plans. Does anyone know if Krebs are the same way? I'd be interested in a pair if they didn't scare everyone else aways.

Wow that's great information. I haven't put anything together yet. Presently building up an antique/vintage cabinet to put it on. I purchased 36 inch length 4 inch diameter food grade tube with sleeves and elbows. I had planned on having the elbows resting on substrate. Tanks side by side with a wood support in between tanks. I planned to have bridge close to top of tanks. I'm open to deciding the length of bridge. That will determine sponge filter and HTBF placements. As for air removal...I have air hose, valve, and my handy dandy Styrofoam around end of air hose for better control. Thinking about adding a length of coated wire for added control of air hose. I've experimented with negative Pressure tanks so my thoughts on that subject. Funny you should mention aptisto because that's exactly the way I was leaning! With chili rasboras on one side. Still thinking the other. Would Krebs be the same? Any suggestions for center piece fish for each tank that wouldn't kill each other? The only thing I have is cardinal tetras I plan to rehome in one of 3 tanks I'm working on. Would like something the cardinals could share in the fish bridge tanks.

So a much shorter tube. Or some kind of emergency run off that my partner won't kill me over. She's let me put 2 in her room 3 in my room. Now this experiment....near her antique furniture in the living room! I can't have a disaster.

Great information. Sometthing to grind my brain on....unless anyone has suggestions?Thanks for your reply! I truly appreciate it. And I DO truly appreciate your response.

Thanks for your reply! I truly appreciate it.

Thanks for your reply! I truly appreciate it.

I am putting together a couple of tanks to be joined with a fish bridge. I have a 20 gallon long tank, a 10 gallon standard tank. My tube is 4 inches in diameter by 36 inches long with bilateral elbows. The question I have is this: Will having one tank being 20 gallons and the other tan 10, will I end up with no negative pressure or if I do, will it all empty into one of the tanks leaving me in a drowning mess? Im not a rocket scientist and physics isn't something I ever took in school. Please advise, if possible.
