    DOS going in reverse

    I have a DOS with one head that is going in the wrong direction. When you press the button to manually activate it, it goes in the labeled direction (clockwise). When it activates on it's own, it goes in the opposite direction (counter-clockwise) on that head.

    Go into the scheduler for that DOS head, click the interval gear, and change it from Remove to Add. Remove causes it to run in reverse.

    Thank you. I can see now that I should have paid more attention to the diagram shown in the AWC task setup.

    I just swapped the tubes so that it is setup as intended.

    My screenshots above are from an article I wrote recently about the advantage of running AWC with both pumps running forward. See https://www.reef2reef.com/threads/fi.../#post-7783633
