"The Romaurie-Effect"

Watch the water level in the aquariums drop as the water level in the "tunnel" rises.The "scat" couldn't wait for the tunnel to fill to get back to his "buddies" in the other aquarium.
The original test rig was with copper pipes, to see if a vacuum would actually lift the water to a usefull working height. It worked but nearly "buggered-up" the company vacuum-pump! So I built my own with a reservoir tank that any water vaced by the set-up goes into and not the pump body.
This system was first aired on "The Fishkeepers" forum in 2004.At that time no one else had demonstrated a practical method to create this effect.In 2007 the "Bottomless" or or "Open Bottom" aquarium was shown but no details of how the effect was achieved.There are some examples on my channel of "stand-alone" aquariums also employing a vacuum to allow the water to flow into the inverted volume.

No. In fact you can "suck" the air out by tube and as long as the lower tank level doesn't drop below the entry level of the inverted aquarium, the water stays in.

As water finds its own level, as long as the entrances are covered by water, any combination of aquarium size could be constructed.I've toyed with the idea of making a "crossover" connection to link 4 aquariums.I'm searching for a reasonable price for the laser cutting.

For details of construction go to "Instructables" The Romaurie Effect.

The Scat [Eric the Scat] out grew this set-up 3 years ago so he now lives in the larger inverted aqurium.

Tried some mollies in the tunnel and its working out very well with the babies being able to avoid the adults by swimming into the tunnel.

You need some plecos.

[romaurie]

I used to keep 2 plecos in this tank, but when they out-grew it I transfered them to the cuboid inverted tank. Good idea, maybe I'll get some small ones for this.

wtf

Your fish is chill.

[mintyman89]

say you were to build an open bottom aquarium using this... if the power went out on the pump, would the water flood out of the bottom tank, or would the suction hold?

[VREDFOX]

nice idea to build a bottomless aquarium, when the air is completely evacuated the aquarium it looks like a transparent solid construction, but fishes moving free inside, great look

[daharshone]

can this be done with two different sized tanks e.g a 240L and a 60L

[profquatermass]

Nice. I've added a small article about your method to the The Aquarium Wiki Encyclopaedia - see 'Romaurie Effect'. :-)
