Excuse me if I get some terminology incorrcet but I am learning. So I have the sump tank set up for overflow in the cabinet. The tank has 3 separate sections : Far left is where the skimmer is set up, return or overflow hose also drains here, nothing in the middle, and to the far right I have a pump? I filled this section up to the blue tape line as previous owner had marked. When I plug the pump up, it sucks the water up and transfers it to the far left section via the overflow hose? You are probably saying well duh thats what it's made for or maybe you are saying that's not what it's made for. If this is what it is made for, then there is no way I can keep it plugged up all the time as it keeps sucking the water down to a very low level causing the pump to make a funny noise like it should when there is no more water to suction. Any feedback or advice would be greatly appreciated. Oh yeah there is also a small fan in this area.
