Kalk Drippers

[LINK]

My pH test kit doesn't test up to anything close to 12 or 12.3, so how do I tell if my Kalk solution is at saturation? How long do I need to stir it (gently of course)? TIA!

anyone know? I kinda wonder as well.

Not long at all. IME, it dissolves pretty fast. I have sometimes left a powerhead stirring it overnight, and sometimes the only mixing is pouring the water onto the CaO. The dissolution rate may depend on the source solids that you are using, but I would not agonize over it.

There are a few ways to tell if it's at saturation, but unless you know that you need saturation (i.e., less Ca++ and alkalinity leaves the tank with dropping levels of Ca++ and alk), that isn't an especially important fact to know.

Conductivity is the easiest way (IMO) to know if it's saturated. pH is another if you have a meter. Ca++ and alk measurement are also ways.
