New Tunnel to test principal of feeding hatches on public aquarium in Oita Marine Park Japan.

great idea , and big bottum tank

The feeding ports on the Oita system where inspired by the combination vac pump - air pump video I displayed.

It was only after careful examination of the Oita system that the holding tanks at the water line were the method of providing the ports.

My small set up was to test a few ideas together.Feeding ports, algae growth hatches for small fish and a "stand alone" tunnel in a single aquarium.

A number of these processes only become clear after running and testing.

feeding ports must be level with lower tanks operating water level.. why do people spend money building things without thinking about physics first?

[romaurie]

The feeding ports are under the tunnel in the vertical passages to the tunnel.They are also under-vacuum.See "The Romaurie Effect" Genesis for the 1st. test I made on this idea.

You might find the current tests I am making on drilling small holes on the water-line to increase aeration to inverted stand-alone" aquariums.The tunnels are not so dependent on additional air input as they can have a water flow through the tunnel.But the principal is the same.

[romaurie]

Now its probably lucky not many realise what I am waffling about.I just realised that the feeding ports are OBVIOUSLY under vacuum.If the top of the tunnel or inverted aquarium were open, atmospheric pressure would push the water out the ports.Because it is under vacuum, only if the water level drops below the ports will air be allowed in to displace more water from the vacuumed section until it again seals the ports.

i think that your feeding hatches are below the tunnel look at the first picture(the one directly after the puke green slide) more closely

I have an idea for how your plan may work. if your interested let me know I may try to make a 3D rendering of it to make it easier to understand. just a theory but could be cool

aquarium in Oita, Vietnam

Due you have a link?

I have been playing with this stuff along time. I build tanks and own a large fish store in Tx.

I have played with tubes from one tank to another with clear hoses when i was a kid. thats when i figured it out. But your feeding hatch deal is interesting to me. I am going to try some things with some scrap acrylic. And would like to look at some pics you speak of.

Would be interested in speaking or emailing more about the subject on the effect.

if so, then there is no way to cut a hole in the water bridge above the water level of the lower tanks because that would be the same as adding a 3rd tank to the system.

Everything connected has to always have the same water level or it will try to even out and collapse all the water out of the bridge

[AlanMolstad]

QUESTION:

So I understand fully - if you connect 2 different tanks with this water bridge, and one of the tanks has a much higher water level than the other, they will always even out?

In other words...

Once all the air is sucked out of the bridge, if you dump more water in one tank the level of the water in the other also goes up?

[AlanMolstad]

thinking about this for a while now...

from what I understand...you can connect two different aquariums with this type of water bridge, but that once you suck out all the air the water level in the two tanks will always be the same...right?

It becomes a water level?

Thus the feeding box opening is actually a 3rd point that must become level with the 2 aquariums.

The guy who helped me cut the glass[I did it myself this time] 6mm safety glass for the lower aquarium thought that maybe we got it wrong.Their system might be "pressurised" or "sealed".But on careful examination of their pictures, I see the hatches are exactly on the waterline of the lower aquariums[holding tanks].You can see net on the top to stop the fish jumping out.They were interested in that idea I used to "pull" fresh air in through the small holes I drilled on the water line.

let me think.....
