Skimmer Calibration
Calibrate the smart skimmer’s pH probe with fresh buffer solutions so readings stay accurate before you return it to the pool.
Tools needed
Have these items ready before you start calibrating.
- pH 7 calibration solution
- pH 10 calibration solution
- Sensor plastic cap for holding solution
- Protective gloves
Step 1 - Plug in skimmer
Remove the skimmer from the pool, plug it in via USB, and confirm the blue charging light turns on before moving to the calibration steps.
Step 2 - Fill cap with pH7 solution
The color of your pH buffer can vary. Some kits include yellow pH7 solution while others use different dyes—follow the label on your bottle.
Wear protective gloves. Buffer solutions are mild but can irritate skin when handled frequently.
Pour the pH 7 solution into the sensor cap until it is roughly one-fifth full. This gives the probe enough liquid to settle without spilling.
Step 3 - Place cap on skimmer sensor
Thread the liquid-filled cap onto the bottom of the sensor and make sure the probe tip is fully submerged in the buffer.
Step 4 - Calibrate in app
In the Clyr app, open your pool location and go to Settings > Calibration. Choose pH7 for the smart skimmer and follow the prompts.
The skimmer should pulse pink while the calibration runs. Wait for the LED to turn green, which confirms a successful reading. A red light indicates the calibration failed and you should repeat the steps.
Step 5 - pH10 calibration
Remove the pH 7 buffer, rinse the cap with clean water, and repeat the same process using pH 10 solution. When both calibration points succeed, disconnect the USB cable and return the skimmer to service.
