Here's a way to "suck" the water from an inverted aquarium system. 4 "hefty sucks" = 10cm. of water. Oral Vacuum.

Discovered that by sucking on the outlet of the water non-return valve, air is removed and the water drawn up. 15 hefty sucks= 1cm. rise in water. Hard work, but for those folks who still ask "why the water dosen't fall down" it graphically displays how and why the water stays in.

The Romaurie Effect was “inspired” by “Bio-Eite’s” acrylic plastic waterbridge. http://www.bio-elite.com/waterbridge.htm http://uk.youtube.com/watch?v=aiRUOAwMpxI And the 2nd link is “How to build a waterbridge” Romaurie.

Perhaps I didn't make it clear in my reply. And as I am still trying to figure out how you made that clever link "NEXT" to the South African Doctor who made the acrylic waterbridge that I saw some 4 years ago now : sent him a couple of e-mails with my idea to put a "ventil" in the center of it...

Try that test with a glass, you will see the glass is full until its open end leaves the water. The resistance you feel is the force of the vacuum. What I am doing with my glass tunnel is removing the air with a vacuum pump so the water is not so much "sucked" in as flowing in to replace the...

I have sent e-mails to Mr.Ho, the producer of the "Fishfreedom" system but have no reply. From the outside it appears to have the same function as the "Romaurie Effect", but if you observe the speed at which the air bubbles ascend, it suggests there is a strong circulating pump. I have tried to...

O.K. If you must have an air stone in the system, a small electric float switch has to be fitted inside the "vacuumed" part of the aquarium.This switches the vacuum pump on and off by way of a small load relay. This can also be used to simulate "tidal changes" in a rock-pool/high water system. I...
