An aquarium is provided with an inflow part and an outflow part, and two
2 pumps are disposed, water level detection contacts are provided in the water tank, and switching contacts are provided that alternately configure circuits each containing two pumps, and the switching contacts are connected to the water level detection contacts; In alternate operation of two pumps configured to operate one pump in turn, an abnormal water level detection contact is provided in the water tank at a position above the water level detection contact, and the abnormal water level detection contact is connected to the switching contact. When the abnormal water level detection contact is activated, it is connected via a control unit that switches the switching contact and maintains that state, so that when the pump in operation stops due to a failure, the other pump can be operated. A control circuit for alternate operation of two pumps, characterized by comprising:
