I have used this system on other projects and realized you really don't need a lot of air pressure to push on any liquid as long as the liquid is not too thick and also the container is not placed too far form the receiving tank.
So Wasserperst what do you think?
I think that has been described first by Mr. Magicmagnihere
and then I sort of repeated it here
. It works very well too, but is a little bit harder to adjust. Note that I removed the drippers and control the pump output via airline valves - much simpler.
