I have been operating the livewell by hand by turning the main aerator pump on and off because it does not cycle with the "MAIN" aerator. Is it supposed to cycle with this pump or is it supposed to cycle with the "AUX." aerator. I fear this will be a problem when summer comes because the battery gets very weak if I let it run the duration of a tournament. Also, where is the timing/timer module located? Any help would be greatly appreciated.
