My Alkalinity is High

[Josh23]

I just started adding Balls pickling lime to my tank two days ago and I checked my Ph, Alkalinity, nitrates, nitrites, Ammonia today and Im concerned about a couple results.
Nitrites 0
Nitrates 0
Ammonia 0
Ph. 8.3 (normal for my tank)

Alkalinity (KH) 190 mg/L which is high according to the the Hagen test book (normal is between 105-125 mg/L). Should I be concerned with this as the PH seems to be within normal limits.
What are you thoughts on this.

Thanks
Josh
