    I want to dose Kalk quantities Night vs Day

    I dose full strength kalkwasser throughout the day and night to account for alkalinity and calcium usage in my DT. ATO just wasn't cutting it because of differing evaporation rates, yada yada yada. So Ive been dosing for about a month now with good success. So I was thinking with the added benefit of Ph buffering that Kalk provides, I think I want to try dosing a little heavier at night than I do during the day when lights and photosynthesis is keeping Ph up. Will this work or is there a better way? All controlled through Apex with one dosing pump in one Apex outlet. The OSC numbers are only representative. I will do the calcs.

    Kalk_Day [Virtual Outlet]

    Fallback OFF
    OSC 000:00/001:00/029:00 Then ON dose 1 min every half hour
    If Time 21:00 to 11:00 Then OFF only dosing when lights on
    If Ph > 8.35 Then OFF
    If FeedA 000 Then OFF
    If FeedC 000 Then OFF

    Kalk_Night [Virtual Outlet]

    Fallback OFF
    OSC 000:00/002:00/028:00 Then ON dose 2 min every half hour
    If Time 11:01 to 20:59 Then OFF only dosing when lights off
    If Ph > 8.35 Then OFF
    If FeedA 000 Then OFF
    If FeedC 000 Then OFF

    Kalk_Dose [Actual Apex EB Outlet]

    Set OFF
    Fallback OFF
    If Outlet Kalk_Day = ON Then ON
    If Outlet Kalk_Nite = ON Then ON
    If Ph > 8.35 Then OFF
    If FeedA 000 Then OFF
    If FeedC 000 Then OFF

    Don't know if I need the Ph, FeedA and FeedC in all outlets. Or would it be a redundant safeguard?
    All comments and reprogramming appreciated

    Your programming concept is good.

    The duplicate If pH and If Feed statements do not provide redundancy so you can remove them from the Day and Night virtual outputs.
    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.
