So once you have your dosing containers and you are ready to dose your two part alk and calcium. So how do you hook them up?
The most common way is to use a simple airline connector. These can be found in any pet store and generally are clear. However, I have found that after time the dosing line hose will stretch slightly causing these to fall of. A better solution is to use a 1/4" connector for garden misting or drip irrigation. These come with barbs on either end which do a better job of holding on to the tubing. They take a bit more effort to install but once they are on they never come off.
