Open Bottom Aquarium

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

Wouldn't fish swimming out the bottom. Or how do you suspend rock and coral

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.

I saw that just a slow typer lol

Really neat idea. You could have a look down and tall column AIO

Right now its a total of about 110 gallons without the sump but thats with a tank that i just had laying around for the upper tank to try it out. All I have to do now it order glass for the upper tank and finish a bit of the cabinetry work. All said and done it will be pretty close to 150 gallons total but you will see about 90 gallons of tank. But when you lift the lids to the lower tank you see the rest of the set up. Its basically going to look like a regular aquarium stand but the tank will look like a glass box with fish trapped inside. Also makes it a 360 degree tank. Great for behind a couch or in the middle of a show room or office.

yes they would swim in and out of the bottom and as for coral you can just build up your rock if you like. I see it being set up as an all fish aquarium though. Right now I have some live rock and coral in my set up but you dont really see it until you look down the upper tank. It is a very unusual look in person. Its almost like there is another dimension to the tank. Dont really know how to explain that part of it

wow, how do you do water change in that thing? seem like a disaster waiting to happen.

I have enough worry about my tank as it is, I would surely not go put hundreds of $$$$ in corals and fish in such a tank.

Interesting concept though, just I would not trust it.
