2-input 1-output "switch valve"

[Geraud]

Hey guys,

I have made a CO2 extractor (using soda lime) for the input line to my skimmer, but would like to turn it on only at night.

So my idea was to to use some kind of valve that would either open a "non-filtered" or a "filtered" (through the extractor) input.

Is there such a thing for 5mm tubing?

Thank you for your input/commentaries

you can use a 3 way solenoid to do this if you want

Thank you!

After some research I found out that I need a three-way multi-purpose solenoid. I have ordered a Skinner/Honeywell from ebay for 20$.

I will update this thread when I set it up.
