Are you using a Kalk reactor? If so, then I would stop using that for now. Waterchanges will also help.
Cross referencing with another test kit can also tell you if the kit you are currently using is wonky.

Where there is chemistry questions, Beverly will soon follow...
 I had the same issue a year or so ago.... and when I calibrated and checked against a pH pen, I found the monitor to be out by 0.5 so I was actually running at 7.95 not 8.45... Now I calibrate once a month or so and concentrate on alk and ca levels... keeping those parameters in line will usually keep pH around 8.2 - 8.4 unless you have too much c02 in the system...
