Dosing container pressure

[LadyTang2]

I am interested in gravity dripping kalk via tubing which allows you to adjust the rate.

The directions on my acclimator drip tubing have you create a siphon but I could see the siphon breaking and it not being reliable for weeks, right?

So I am left with cutting a hole in the bottom of a container and dripping from below using gravity rather than siphon. But I know when the container is full there will be more pressure and the rate will be faster, and when the container is near empty the rate will be slower since there is less pressure. Is there anyway to account for this?

Any special containers thats somehow make it so the pressure does not change? Any other ideas?

If your container is not real tall the difference should be minimal. Kalk will clog any sort of drip tube reducing the flow more.
