How old is the tank? I assume it has corals also?
Should do a larger water change, and does something like sodium bicarbanate or soda ash.
I would be less worried about the zero phosphates because if you are feeding, some are entering the system naturally. Hold long ago was the last time you tested?
Interested to see what other advice is offered here.

5-10 mL of kalkwasser is useless.
You need to dose 1 gallon per day to add 1 dKH to 125 gallons of tank water.

Don't worry about the calcium level when using kalkwasser. Yours is fine for now.

Ensure your MG is in the 1350-1400ppm range or you may get some wandering Alk test results.
The Hanna CA checker I’ve had no luck with. Always higher than expected and wandering results.

If alk is lower than you want, then add more.
