PH plummeted...?

[koa25]

Dropped the probe in my ato. Went up to 9.87ish. Went and bought a test kit. Ph is right about 8.0 according to the test kit and 3.93 on the probe. So it twas a bad probe. Now the headache of returning it begins. Appreciate the help guys.

have you calibrated the probe?

I calibrated it when I first installed it a couple weeks ago. It shouldn't have gotten thrown off that quickly. It was brand new and came with the packets.
