Pressurized Kalk Drip

[6stokes]

I made a five gallon pressurized kalk doser this past weekend so it could be hidden under my tank stand. My question is, since it is continuously pressurized with air, is too much carbon dioxide being made available to the mix before it has a chance to enter the tank?
Bang Guy... :help:

Is there only enough air in there to keep it pressurized or is it a continuous supply? If the tank is jostled much then the film off Calcium Carbonate won't break and should protect the limewater from CO2. Just make sure you're not bubbling the air through the liquid.

It is a continuous supply, but not bubbling through the water. And my first batch did make a film on top. So I guess as long as it doesn't get moved around to break that film, I'm okay?
That brings me to another question. Do I now need to monitor the level so it doesn't drip that top layer when the tank gets low? Or, do you think it's a thin enough layer that it will break siphon before much of it gets to the tank?

I believe the film on top will protect the limewater.
If it's under pressure, then there's no siphon to break. It's important to not allow the silids into your aquarium. A little bit isn't a disaster but it's not a good thing especially if you're not using lab grade Kalk.
Is there any way to maintain pressure by pumping limewater into the container instead of air?

You're right, I used the wrong terminology. It won't break siphon, but it will stop forcing the fluid once the water level drops just below the dip tube. I have the tube located about a half an inch above the bottom of the container. I'm not sure how I could force the fluid into the container instead of the air.
Basically, it's a 5 galon gas can with a dip tube to the lower level and a tube above the waters surface to pressurize the tank. The lower level dip tube has the drip line attached, which drips into my skimmer intake cup.

Sounds fine. But it's best if you keep it from going enpty.

Once again, thanks for your help.
