Super king and Supermaster were my first filters. I still keep the boxes, but the motors were long gone. They are outdated and replaced by much more efficient magnetic driven motor pump. The one OP shown uses about 70 watt (115V x 60A), 10 times more energy than an AC110 or a Penguin 350 with less pumping rate and the media capacity is no more than either filters. Moreover, it makes loud toilet flushing noise and a pain to start the siphon. Trash the motor and use the box to hold fish and stuff.
