What are you using to measure pH? That pH is possible, but unlikely, so I'd first question testing error....either in the test kit or pH probe. If pH probe, have you calibrated using pH 7 and 10 calibration solutions?

If that reading is in fact correct I believe vinegar can be used to lower your ph.
