Solenoid for ATO

[njoyreef]

Hi reefers,
I am in the process for a new build.
Can you pls. Help to recommend a reliable solenoid that I can connect to GHL power bar and program it.
I am looking for simple ON/OFF function without any fancy controller..

Thanks in advance for your help...

Joy

There are multiple kinds of car solenoids that can be used depending on application. I know brs has some suggested when you watch the co2 scrubber video.
They are usually closed solenoids and work well. I set it to open my co2 scrubber when ph hit a specific point.
