no it gets trapped in there. Once the tank is displaced with water it will stay there unless something can take its place. Being that the tank is a sealed chamber it stays suspended in the tank. Its the same science behind the old upside down cup in the kitchen sink. Fill the sink and turn a cup sideways till it is full of water. Then turn it upside down and pull the cup. Presto the water is suspended in the glass. Same idea here.

Seems like an interesting concept, the only thing I'm confused about is how you would remove the air pocket?
Simple as sticking airline tubing up there and sucking?

I dont displace the tank that way though obviously. Be a lot of weight. Ive seen people use an air hose and suck the air out while water in the lower tank replaces the air. I have a special pump to do it though. Ive had a quick set up going for a month now. I just wanted to try this idea out before I ordered the glass for the upper tank. The lower tank and cabinet have been built already

I've seen this before but don't think it'll work we'll with saltwater. You won't be able to run a sump or skimmer. The bottom tank is gonna be too shallow for a hang in back skimmer
Plus you'll need a very accurate ato top off. If air gets into the top tank you'll have a major flood

actually I am running a sump with mine right works the same as any other tank. As for the big mess im not to sure how that would ever happen. Other than the upper or lower tank breaking. Be the same mess if a regular tank broke. But lets just say there was no sump and as the water evaporates the level would drop in the lower tank reaching the brim of the upper aquarium. Thats where you think you lose your hydrostatic pressure and the upper tank would dump its water volume making a mess?? It doesnt though. What happens (cause i tested this out) the upper tank does a big burp or gulp if you will for air until the water rises in the lower tank, goes above the brim and then stops. Its all really quite simple and fool proof.
