## Chemistry Monitoring

If you would like to monitor the pH/ORP/Temp in your pool, please order the Clyr Chemistry probe and this probe is compatible with both Clyr Lite and Clyr Controller versions.

You can buy the inline probe here: <https://www.clyrpool.com/inline-sensor>

## Filter Monitoring

If you would like to know when your filters are dirty please order the Clyr Digital Pressure Sensor. The sensor also enables other safety features such as Pump Protect, which automatically sends you an alert if it detects that the pump is malfunctioning due to air in the system. This protects your pump from burning up and having to replace an expensive pump.

You can buy the pressure sensor here: <https://www.clyrpool.com/pressure-sensor>

## CO2 Dosing for pH Balance

If you would like to automatically keep your pH balanced in your pool, please order the CO2 dosing regulator and purchase a 20-25 lb CO2 tank that can be refilled at any welding store.
