    Is this correct for stopping my carbon dosing if PH below 7.95?

    I have a peristaltic pump connected to one of my outlets, it turns on every 2 hours for 23 seconds. Just realised that I want a safety in there to stop it if PH is below 7.95. Does this look correct? Thanks for looking.

    Fallback OFF
    Set OFF
    If Time 07:00 to 07:01 Then ON
    If Time 09:00 to 09:01 Then ON
    If Time 11:00 to 11:01 Then ON
    If Time 13:00 to 13:01 Then ON
    If Time 15:00 to 15:01 Then ON
    If Time 17:00 to 17:01 Then ON
    If Time 19:00 to 19:01 Then ON
    If Time 21:00 to 21:01 Then ON
    If Time 23:00 to 23:01 Then ON
    If Time 01:00 to 01:01 Then ON
    If Time 03:00 to 03:01 Then ON
    If Time 05:00 to 05:01 Then ON
    Defer 001:37 Then ON
    If pH < 7.95 Then OFF

    I would not do it that way. Do this instead if you want every 2 hours starting at 1am.

    Fallback OFF
    OSC 060:00/000:23/059:37 Then ON
    If pH < 7.95 Then OFF

    Thanks Zombie, I will swap to the OSC method once I have finshed tinkering with the right dose and times needed. For now, does my code look correct? Specifically the PH part. I was unsure if I should put that line above or below the code?

    Use the OSC method anyway. You can tinker with the times easier with OSC.

    Ok, will give it a go later. So either method needs the PH line under the rest of the code?

    Yes. Overrides always go further down in the code than normal behavior.
