    Feed Timer Skimmer Programming - What am I doing wrong?

    So I discovered dosing Red Sea Reef Energy A+B causes my skimmer to go nuts. Who would have thought dosing nitrates would make your nitrate scrubber do its job? In any case, I want to turn off my skimmer for two hours after I dose it. I thought I did everything correctly but when I push my Feed Cycle B button it starts to count down two hours but the skimmer never turns off. In the screenshot below you can see the timer is going but the power chart still shows the skimmer on and I verified by looking at the skimmer that it's still bubbling away. What am I doing wrong here?


    Fallback OFF
    Set ON
    If FeedA 000 Then OFF
    Defer 005:00 Then ON
    If FeedB 000 Then OFF
    If Output RetPump_2_3 = OFF Then OFF
    Defer 005:00 Then ON

    Did you make sure the skimmer is in AUTO?


    This wont effect the issue at hand, but you have two defer then ON statements and the apex can only use one, which applies globally. Delete one of them.

    Ah, no! I have the skimmer set to ON. So I'll switch that over to Auto. Thank you Zombie.

    So does that mean no matter what condition is over the defer 5 will always be applied because there can only be one ON statement? Since the return pump turns off for Feed A and I want my skimmer off if the return pump dies or power goes out I wanted to always defer the skimmer from turning on before the sump level goes back to normal.

    Yeah. The defer applies for any condition that would turn the pump from OFF to ON.
