OK, trying to calibrate my pH and either I am doing it wrong or I have a defective probe.
I removed the clear latex cover ( I assumed I should since it was airtight)
I placed the probe in my tank
It read over 12.
So I got some rodi water and some calibration solution (7 and 10)
I went to setup>ph calibration>ph>7.0 calibration
I dipped the probe in rodi water for 10 seconds, wiped it off, placed it in the 7.0 solution, and waited.
No change...12.73
Finally I hit select, selected 10, rinsed the probe in rodi, placed it in the 10 solution and waited.....................................................................................................................................................................12.73
OK, I hit select..........................................................................................................................................................Defective probe.
Am I doing something wrong or is the probe defective?
