    Will this code work form my ALK dosing? I think Something is missing based on my Output logs.

    I wanted something easier to understand and easier to tinker with while dialing in my ALK dosing. So after reading online I saw where someone programmed their doser to come on using the 'If Time' command. That made for a practical and easy approach for me. So I plugged it into my doser. I use the BRS dosers. However, I happened to look back at Fusion and for some reason my dosers came on at 10 am and I don't think they went off until I turned it off when I saw that it was on at 1pm. Am I missing a code?

    Fallback OFF
    If Time 00:00 to 00:01 Then ON
    If Time 02:00 to 02:01 Then ON
    If Time 04:00 to 04:01 Then ON
    If Time 06:00 to 06:01 Then ON
    If Time 08:00 to 08:01 Then ON
    If Time 10:00 to 10:01 Then ON
    If Time 12:00 to 12:01 Then ON
    If Time 14:00 to 14:01 Then ON
    If Time 16:00 to 16:01 Then ON
    If Time 18:00 to 18:01 Then ON
    If Time 20:00 to 20:01 Then ON
    If pH > 8.50 Then OFF

    Yes, you are. There is nothing to turn the outlet OFF. You must have a Set OFF in there:

    Fallback OFF
    Set OFF
    If Time 00:00 to 00:01 Then ON
    If Time 02:00 to 02:01 Then ON
    If Time 04:00 to 04:01 Then ON
    If Time 06:00 to 06:01 Then ON
    If Time 08:00 to 08:01 Then ON
    If Time 10:00 to 10:01 Then ON
    If Time 12:00 to 12:01 Then ON
    If Time 14:00 to 14:01 Then ON
    If Time 16:00 to 16:01 Then ON
    If Time 18:00 to 18:01 Then ON
    If Time 20:00 to 20:01 Then ON
    If pH > 8.50 Then OFF

    Do you realize that each If Time statement will turn the dosing pump on for 2 minutes at a time, not 1 minute? If not, read this: https://forum.neptunesystems.com/sho...ll=1#post97230

    You should really be using OSC for repeated dosing at fixed intervals than a lot of If Time statements - it's easier to use once you get the hang of working with the OSC command. And this web page makes it easy to get started with using OSC: https://www.reeftronics.net/adpg/
    Please do not send me PMs with technical questions or requesting assistance - use the forums for Apex help. PM me ONLY if the matter is of a private or personal nature. Thanks.

    Ouch! Dang oversight. Just rushed home to check the damage. Fortunately the tank looks okay. But had a huge spike. Went from about 8.2 to 12.6. Making water for a water change!
