Connected Tank Idea- Feedback please

  • We are currently upgrading MFK. thanks! -neo
i can do it for $11 using 4 elbow pieces of 3" pvc ($2.68 each) but that would mean a solid white material.
these pieces, except one end is male, other female so they connect to eachother.

so i can make:

i might even just go to a plastics injection molding company that i have some connections at and make a bunch of these to sell. there must be tons of people out there that have many small tanks instead of ever investing in a larger one.
 
has anyone actually purchased that e-book on the fish highway? i understand the concept. i mean it works the same as my overflow in my 125, but how do pressures and vaccuums come into play? just curious but not 9.95 curious.lol.

The idea here is pretty simple. Imagine that you were siphoning water out of your tank into a bucket. The bucket is obviously lower than the tank (it's actually the end of the tube that matters, but for simplicity's sake).
Now imagine lifting your bucket so that it becomes higher than your tank. What happens? The water starts flowing the other way from bucket to tank. Now, lower the bucket so that it sits beside your tank. What you are doing is finding that sweet little golden spot where the flow in the siphon isn't going in any direction. All that needs to happen is both ends of the tube need to be at the same height. Now imaginarily expand the tube to a size that fish can swim through, and voila.

We were taught this back in elementary school- get a bucket of water, and a see-through cup. put the cup underwater so it fills up with water. then, lift the cup partially out of the water, bottom end first, keeping the open rim of the cup under water. the water doesn't spill out of the cup, because there is nothing that will displace it. you could do the same thing with a tube/airline in your aquarium. stick the whole thing underwater so that it's filled with water. lift somewhere in the middle of the airline out of the water, while keeping the ends of the tube underwater. water stays in the tube, above the tank's water level. hope that helps.

I meant if you were going to shoot water from one tank to the other with a powerhead via water bridge, wouldint it?:screwy:
Sorry, I guess I wasn't clear. I meant that the powerhead would pump water to the other tank just through a smaller tube, separate from the water bridge thing. so there would essentially be 2 bridges- one small bridge that water is forced through, and the large fish-accessible bridge that would bring water back, due to the atmospheric effect of bringing the connected bodies of water to equilibrium.
