Kalkwasser powder: How often to add to reservoir
I'm using a reservoir, not a kalk reactor.
Am I supposed to add kalk powder EVERY time I fill the reservoir with fresh water?

Yes. How much are you using per gallon ?

I use the same method. I over used my kalk, i was just using a big serving spoon and i was making sure i had enough i guess. I found myself with about 2 inches of lime in the bottom. I have been adding fresh water to the lime that is sitting, trying to use it up, is that ok?
Sorry to hijack if i did, i think it is related to what nerd is asking. |

Yes that is fine but you should try to limit your additions to 2 tsp per gallon of water.
Depending on the brand of lime used, the impurities can settle to the bottom and should be avoided for adding to the tank. |

If you do have excess solids remaining on the bottom, you may not need to add new lime every time, but bear in mind that some solid that remain are not lime, but residual materials like calcium carbonate that won't dissolve. If you measure the conductivity of the limewater, it is easy to know the potency and whether you need more solid lime or not.

Can the conductivity be measured by any standard conductivity probe?
If the probe can read at 10 mS/cm, then yes. Some can and some do not (only reading lower values, in some cases).

Taggin along. Curious about how you measure conductivity.

With an electronic conductivity meter. Pinpoint sells two, and only the salinity meter reads in the right range for limewater, the other is for RO/DI purity.
