This weekend I made a run with my livewells in the AUTO position. I got to the next spot a few miles away and decided to add some Rejuvinade while I was idleing in to the cove and the wells were empty. ...Do the pumps have to be on to use it in the auto position? I was using them on timers...Also, does anyone else have the issue that the overflow drain is the same height as the aerators and it fills so high before it drains, that the aerators can not spray a stream into the water?
