pH swing during water change a concern?

The pH change from a water change is not a concern.

I will stick with Kent. Always mixes clear for me. I usually mix 50 gallons at a time and use it for w/c over the course of a month. Tests stay stable, and it stays clear.

It might be coincidence, or maybe you stirred something up with the change. Water changes do not normally cause issues.
