CO2 Solenoid – Spring Switch Replacement

This listing includes a replacement piece for the solenoid ONLY.

If bubbles continue to diffuse after the power is turned off, this replacement part ensures your solenoid functions properly and fully shuts off.

A solenoid is what will turn your regulator on and off. This is an integral part of an effective regulator because leaving CO2 on in your aquarium will lead to PH fluctuations. The solenoid gives you the ability to plug it into a timer to avoid PH fluctuations that may harm other organisms in your aquarium. This replacement part is compatible with both UNS CO2 Regulator models.
