Not a hoax. That guy has more tanks than that. I'll have to look for links.
If I remember correctly, the top is sealed. Similar to an upside down soda bottle hooked to a dog waterer. Air is pumped from the top down to the bottom (the bubbles) so the pressure stays constant. Something like that.

Do read minds also
man if thats for realsss I am going to work !!!:beer: 1.Oxygen reactor
2.Atomizer
3.Denitrator with a hydrogen sulfide electric generator (use nitrates to generate electricity)
4.That fish tank has me
or is the:beer:

if the top is sealed then it's truly really simple physics...go get a coffee cup, fill it with water to the brim...put a piece of plastic over it, flip the cup over, take off the plastic and the water will stay in the cup!
I don't think the top is covered though because it looks like water is splashing into it aka air and if air was being introduced to a airtight chamber, eventualy the water would drain down. for every volume of air introduced into the closed chamber...that same volume of water would go out the bottom.
the only thing I could think of, which might work...would be that the air pressure pushing down on the whole lower section of the tank was enough pressure to push the water up that tall section. but again I think that would need to be sealed.
it's got me!

You can see air at the top and the bubbles are breaking surface. An upside down bottle still holds water even if it is half empty.
Haven't had time to look for this guys other tanks. He has one that is outside like in a courtyard and the fish are swimming through channels and then go up into cubes that are sitting around.

I found the thread where the link was/is to this guys outdoor tank but I guess he made it private.
Anyone know how to crack it?

I've seen this video many times in the past along with another by a different aquarist that has "tunnels" running up and down around the walls of a room.
Wish I could find that one again.
(LOL, I just took another look at the link in the first post above and saw my comment on the video from a year ago, the 10th one down, asking about a closed loop on the airstone. He still hasn't answered me. Hahahaha.)
It's a very cool and simple concept.
The one thing that always seems to confuse everyone is the airstone.
There's two ways to achieve that effect without dumping the water.
The "not-so-smart" way: I saw another of fishfreedom's videos that showed the vacuum pump hooked to the schreider valve drilled into the top of the tank which ran at the same time as the airstone.
Airstone introduces outside air, vacuum pump removes outside air.
Air volume and water volume inside inverted chamber stays constant.
The "smart" way: Airstone pump draws air from top of chamber and pumps it to bottom of chamber in a closed loop.
Volume of air and volume of water inside inverted chamber stays constant.
