i am 99% sure my pH probe for my pH controller isnt functioning. I turned off the Co2 for now just to be safe. According to the pH controller, the pH would never get below 7.0 even after running CO2 for 5+ hrs at about 5-6 bubbles/sec. It was at 7.0 for over 3 hrs. I did a pH test with liquids and it was between 6.0 and 6.4 (leaning more towards the 6.0 side).
What should I do?
