PH - should I be concerned?

[acrocapital]

Recently started dosing Kalk (as in yesterday). Before dosing my PH peak was 8.43 - 8.45 with a low point of 8.27 - 8.33. After starting dosing my peak was 8.61 with a low of 8.40.
I have calibrated all of my probes 2 weeks ago, and recently bought a brand new one for my CARX and calibrated that as well (with 4 & 7). Hanna handheld checker is ~.02 off from the probes. I would say accurate enough.
I attribute most of this high PH with the fact I run my alk very high, 11-12 is usually my target. This is the system that's in the garage there is lots of forced ventilation, garage door is also opened many times throughout the day, & skimmer intake is pulling from outside, it is practically as if the system running outside.
Is this too high? Should I be concerned with the numbers I am seeing?

I mention the new CARX probe because I put that in the main system temporarily to verify my other probe is accurate, the CARX probe matched my main PH probe. Surprising because I calibrated it with the lower range, I didn't think it would be accurate at the higher range.

The values are ok as long as you do not begin to get excessive precipitation of calcium carbonate on sand, pumps, etc.
