Introduction: "Romaurie-Effect": Inverted Aquarium in Shallow Base Aquarium.
This details the design and set-up of a vacuum-filled aquarium.
Step 1: Draw a Plan of the Aquaria With Dimensions for the Glazier to Follow.
I've chosen a relatively simple inverted aquarium that sits in a shallow base aquarium as opposed to the "tunnel" that links 2 aquariums with a vacuum-filled "water-bridge".
I've enclosed drawings that you can either have a glazier construct or cut and you assemble.
Step 2: Setting-up the Finished Aquariums.
The various processes leading up to this are thoroughly documented on "youTube".If after those details of how to build your own vacuum pump you don't feel happy to make the vacuum yourself, "tap-up" your friendly neighbourhood refrigeration engineer to make it for you.
The valve assembly on the top is a garden-hose adaptor with a refrigeration schreider valve screwed into it.It is also possible to feed a semi-rigid plastic tube to the top of the upper aquarium and vacuum through this. When the water reaches the top, shut-off the vacuum-pump and remove the tube. The water will remain in the upper tank as lon as the lower tan level covers the entrance to the upper tank.
Step 3: Schrieder-valve + Garden Hose Connector Details.

Also shows "leak-testing" the upper aquarium.If there is a leak, air comes in [note the air bubbles in the corner] this can be marked, water emptied, dried and re-sealed.
