I just calibrated the probe before I got these low results. Before calibration, I was between 8.3 - 8.7, as far as the probe said anyways. Does calibration solution expire? I've had it for about a year and half. It was sealed.
I'm hooking up a CA reactor soon, and want to make sure my probe works. and that my levels are good.
