How to fix unstable pH readings on my Maytronics Controller?
- Ppaul63Aug 12, 2025
If the pH readings from your Maytronics Controller are unstable or inaccurate, it might be due to several reasons: * The pH Sensor may be dirty: Disconnect the pH Sensor, unscrew it, and gently wipe the glass bulb with a soft tissue soaked in methylated spirits. Then, soak the tip in diluted Hydrochloric acid, rinse thoroughly with clean water, and reassemble. * The pH Sensor may need recalibration: Clean the pH Sensor as described above and then recalibrate it. * The pool water might have low conductivity: Add one bag of pool salt per 50,000 Litres of pool water.
