That isn't true. As long as both ends are in the water and the water is pumped or sucked out it will be fine.

This would require a good knowledge of physics and a good calculator.

The physics behind it are that gravity is going to make the water equalize. So if tank A's water level is 5 feet above the ground, and tank B's water level is 4 feet above the ground, the water is going to probably siphon 6 inches of water out of tank A into tank B making both water levels 4.5 feet.

Now knowing that, if you wish to put the tank on separate levels you have to cancel out the siphon with a pump that puts the water in the higher tank with the same rate of flow or eventually one will overflow.

Not impossible, but not easy.

That's a good point , to have them separate heights the pump would have to push against the weight of the water in tank A, most of but not the entire weight, i don't think you would find a pump strong enough to keep the levels the same plus why wouldn't you want them level.

And with the water flowing from A to B, all the fish would eventually end up in B and be unable to fight the current.

Plus it would make quite a mess.

Lol, agreed.

What if he was able to replace the glass of the inner walls with Acrylic which would be easier to fabricate?

Would that be possible? I have never tried to mess with a tank frame but I figure it's mostly A-frame metal, glass panes, and special acrylic caulk holding it all together.

I've never messed with a tank frame either but I think Acrylic would definitely be best, your most likely right on its construction. I think its a type of caulk designed not to leech chemicals into the water.

Do you think a glass tube would even be able to handle the stress?

I would definitely want to use an acrylic tube. It would ebb and flow better with temperature changes and friction against the 2 tanks.

That would work but it would be cool to see in the tube.
