pumping water without electricity?

So I want to build an aquaponics system, because they're awesome, but I need a way to move water about 6' verticaly. I dont have elctricity where I want to put it, and there's not going to be. The water needs to be moved from the bottom of the fish tank, to the top of a resivoir tank. I want to buy the least amount of stuff possible for thisproject, so I could use some help:D

I use low pressure air to pump water with an airlift pump. It needs about 1 psi of air pressure. I do use an electrical bubble pump for an aquarium to make the low pressure air but I could use a stream and tromp ( no moving part air compressor). I made a tromp on a little stream years ago and it produced between 11 and 15 litres per minute of 3 psi air. This would be enough for about 30? of the airlift pumps shown in the video. I plan to make proof of concept for this compressed air produced by tiny wind power and tiny solar Stirling and fluidyne pumps later in the year. https://www.youtube.com/watch?v=8pI31ZwEL40 And it pumps to well over 6 ft high too.

You might be talking about a water ram. Check it out here: http://www.rampumps.com/index.html

I also want to run an aquaponics system without using electricity. I'm not electronical minded and even though I love this website and want to make everything, that said I am only an artist so my question may sound stupid. Is there a way the Tesla CD Turbine could run from the pressure of the water draining from the above food tanks to the lower fish tanks or be used with any of the above suggestions?
There most likely is, but because of the law of conservation of energy, you will only be able to pump "part" of the water back up, using any generated electricity, etc. In other words, the system will stop after running for a bit, unless you add energy (water from a hose or pumphouse, or whatever) from the outside of the system.
After looking at the 'World's Greenest Water Pump' found on this site I am now wondering if I could use that instead. We live up on a hill and if we place the pump down low do you think the pressure of water draining down to the pump (instead of the pressure from a creek or river) be enough pressure to run it. We have a drop of at least 15 feet that we could use. Thanks for your imput!

I was thinking somethin along those lines, except I don't know what I could use for the "pump of some description"
How about...

A vertical axis turbine (like a savonius or Lenz), with a universal joint beneath.

The universal joint is connected to rotate a shaft at 45° to the vertical.

The end of the shaft is in the lower tank, and wrapped around the shaft is a length of flexible tubing (such as hose pipe) - it's a wind-powered Archimedes screw!

haa I already thought of that one...It needs to be vertical, because there isn't enough room to put the screw.:(

OK, then a horizontal-axis pump with a cam driving a stirrup-pump, or a small peristaltic pump.

is there an easy way that I could make a peristalktc pump?Or would i have to buy one?
It depends on your skills and/or budget.

Have a look at what they are.

There is a video of how to make one here, and a design sketch here.

would a pump like thay be capable of pumping water 6'vertically?
.  Being a positive displacement pump, a peristaltic pump's lift is limited only by the strength of the materials of construction. Six feet is no problem for all but the weakest of peristaltic pumps.
They should be, yes.

Hydraulic ram
Photovoltaics (to drive electric pump)
Wind turbine (as per Kiteman)
Hand crank pump.

Theres no flowing water at the site, so the hydraulic ram wouldn't work, I dont have money for photvoltaics, and it would be too inefficient for the system for a hand crank.

If you're OK with intermittent pumping, try a small wind turbine mechanically linked to a pump of some description.
