How do I turn off CO2 during feed pause?

[Zonian]

I have a planted fresh water aquarium and add CO2 via a CO2 reactor. I have set up a feed pause that shuts off my canister filter. I use programmable logic to control CO2 via pH probe and a timer. I would like to also have CO2 off during the feed pause. How do I do this? Thanks.

You can do this by creating a new PL gate.

1. Go to the PL settings page and choose an unused gate
2. Set the function to AND.
3. Set Input 1 to the PL gate which contains the pH probe and timer function.
4. Set Input 2 to Filter and choose the feed pause number, then save settings.
5. Go to the Switch Channel page, choose the socket for your CO2 reactor, set the function to the PL gate you created in step 4.
6. Save settings.
