What to do if my Zodiac pH Link Lighting Equipment shows 'PH LOW'?
- DDouglas ReedAug 25, 2025
If your Zodiac Lighting Equipment displays a 'PH LOW' error, it indicates the measured pH is 0.8 units or more below the set point. First, check the pH in the pool. You should also check the set point and the selected pool size. Clean and calibrate the pH sensor, or replace it if necessary. Finally, replace the pH7.5 buffer solution if needed.
