High PH 8.5 alakanity 7 and kalwasser

[ajiisss]

I was dosing kalkwasser in ATO and I found my PH is always high so I stopped kalkwasser for few days but my alkanity is 7 now dropped from 8 (Hannah checker).
I want to keep it at 8 if I dose kalk again will it also raise PH? or should I go with 2 part. I don't have many corals

I wouldnt mess with kalk unless you have low pH.

You should do weekly water changes and that should keep your tank stable until you start getting more coral. Then i would look into 2 part dosing with baking soda and calcium chloride when water changes wont keep up the replenishment.
