New flow idea

[Jaws]

I'm always thinking of new ideas to create random chaotic flow in a tank. One thing that I would really like to achieve eventually is having no powerhead or flow devices in the tank such as tunzes, seaswirls, etc. The only way I can think of doing this is a very powerful closed loop system that has the outlets hidden amongst or behind the rock. I've wanted to test this theory for a while but don't have the means to do so yet. What about leaving a couple inches between your rock and the back wall and aiming your closed loop outlets straight up say behind your rockwork. You could either drill the bottom of the tank close to the back wall for each outlet or just have one pipe coming in from a side wall and run all along the back wall with multiple outlets. If the flow is pointed up then once it breaks the surface it has no choice but to disperse and travel outwards and back down. This will also create a lot of surface agitation and create all kinds of light refraction. If the upwards flow is along the back wall too then theoretically the flow should travel down and towards the front of the glass which is how most of us aquascape our tanks. The only thing I'm not sure is if the downward flow would be enough after it breaks the surface. If you had some kind of peninsula type aquascaping with a three sided viewing tank it would be neat to have a number of 1" outlets pointing up from various points in the rockwork and then maybe still have some pulsing lateral flow sweeping across the rockwork in order to smash into the vertical flow and create some chaotic flow. Just a couple ideas I've been pondering. Not even sure if it would work but I would be interested in some other people's opinions.
