This now has me concerned as I’ve read that dosing kalk can be very tough on optical sensors. Because of this, I’ve been considering switching over to the Spectrapure or Avast ATO systems because they use pressure switches instead of optical sensors which can get fouled with kalk.

Am I overthinking this? Should I hold on to my trusty Tunze Osmolator or switch to a pressure switch ATO set up? For those using dosing kalk with their Tunze Osmolator, have you encountered any problems with the optical eye getting fouled?
I've used multiple Osmolators over the years and never had issues with the optical sensor getting scale on it. I've used the pump directly in the kalk reservoir, elevated above the sediment of course. Tunze doesn't recommend it as it wears on the pump, but I've found that the pumps still last a really long, plus they're cheap to replace. I have also used the Tunze Kalk Dispensor successfully. With all of that said, I still prefer to dose kalk with a Litermeter. No chances of an accidental overdose and each dosage is nice and small.
