Can anyone please explain to me how Recirc works? In my mind that means it circulates the water in and out of the livewell. However that does not seem to be true, all that seems to happen is water is pumped from my livewell back into the lake, nothing "recirculating" or refilling. This to me is extremely confusing more due to the fact that the Oxygenators are wired into the recirc pump. Why would I want to restore oxygen into water that is just going back into the lake? Am I missing something? Is something wrong? Any help would be greatly appreciated
