Does Anyone Reuse Kalk Slurry In ATO

Are you asking if you can reuse the sediment? If so I thought you could not.

I just add more fresh Kalk to the ATO....The sediment does start to build up after awhile, but isn't water soluble so it will not affect your water. It is however extra wear and tear on your ATO/Kalk mixing pump(if you use a pump) I drain it, and clean the Kalk reactor about once every 6 months or so, just to get the sediment out
