ok i figured this out in the old thread but i will repeat.
the air pump is out side the tank above the top of the upper tank.
i tube goes from the air pumps intake down under the the tank and up the back behind the back ground to the top of the inside. there it sucks in air and it goes all the way down and out to the air pump and back to the out port. then it is pushed back down and into the bottom of the tank to bubble up the the top to be sucked up one more time. if the power goes out no big deal as the air pump is above the waterline and the bottom air tube can not suck air. the only problem is the top air line HAS to have a check valve that will not let air travel into the top of the tank. it would NOT be using a plastic bendable pipe, but a stronge PVC or better a metal flex pipe like the ones used in a vacuum system in a car.
the air bubbles add no O2 to the water but are just to move the water, all aeration must be done with the lower tank. this is no different then a very deep tank with a small surface area at the top, you just need a way to mix air and water better. a over flow and a big sump system under the lower tank could deal with both the O2 problem and any overflow issues.
if you had a strong enough air compressor i could make a top tank go up and down like a huge tide
just put it on a timer !
still this is about a gimmick tank and much less about the fish.
