A "Romaurie Effect" process timer controlled vacuum pump to provide extra air flow via holes on the water line interface between vacuumed and positive pressure aquariums.

Hi you really have quite a set up there well done,

are those tanks all inter-connected? You got one hell of a set up.

Yeah all I can say is whooly crap, my wife would kill me.....

Each aquarium set-up has its own external bio filter.I have been using the plastic water filter cases for home drinking water but modified to hold carbon,ceramic tubes and gravel.They work very well and I have a mechanical filter to catch debris before the water returns to the filter.
The inverted aquariums use a circulating pump to to move water from the open area to the vacuumed area thus providing oxygen.The process timer also activates a vacuum pump to draw in extra air.

We only have 1 small set-up indoors.The large systems are in a purpose built housing for the set-ups.
