Could someone explain this to me?

Hole in the middle of the tank....

I know its been posted before but no one could say how it works....

How does it work?!?!

The tank is sealed at the top - no air can enter the top, so no water can get out.
If they ever get a leak at the top of that thing, LOOK OUT!

Works on the same prencipal as my calk doser. sealed container above my sump. Sump level drops and air enters the container. Calk flows out till sump level reaches the hole in the bottom of the container. Like a glass turned upside down under water then lifted 1/2 the way out of the water. The water stays in the glass.

I can easily see this working in a static model but in the real world I am having a problem figuring out how they keep the vacuum maintained. Any additions to the tank like air bubbles or water should end up displacing an exact volume of water out of the feeding holes. I wonder how the pumps work, they must have to be ever so careful that no micro bubbles are entering the tank.

BTW while I agree it's cool looking, but it's an absolutely crazy idea. It's right up there with hanging a vho Ballast with tie straps right above your tank. It may work but sooner or later...

PrivateJoker64 hit the nail on the head. It's sealed at the top so that no air gets in therefore creating a vacuum. As far as a pump goes, as long as it is a closed loop, it's fine.

I'll bet there's a way that they seal the feeding holes so that they can upen up a service door or port (like on a submarine) to service the inside of the tank.

Henry just imagine what would happen if a pump hose leaked and started jetting micro bubbles

It is a really neat idea, but I wouldn't trust my fish in that. Any little pin-hole, and it's goodbye fishies. Besides, how could you possibly deal with gas exchanges. You need oxygen to get in and nitrogen to bubble out.

 

[Henry Bowman]

Yeah, I dont thing God made enough buckets ! Wonder if their insurance covers water damage or flooding...

 

[daytonians]

You know, that reminds me of those water filled barometers. The water moves up and down in a tube depending on the air pressure around it. A sudden drop in air pressure would probably make a messy floor.

Looking at the first photo, isn't that water on the titles or is it just partially waxed with a high gloss finish?!?

Cool, but not in my house...

Yes, you can see water on the floor in the first 2 pics.

I yhink he just hosed the floor off, you can see the garden hose.
