Just picked up a used 10 gallon aio tank to use as a frag tank. Dimensions are about 20”x20”x8”.

It came with a cobalt aquatics MJ-1200 as its return pump. Upon plugging in the pump, it seems to be releasing electricity into the tank. Got a very small shock when placing my hand into the water. This was the only device plugged in.

I can’t seem to find a replacement cobalt MJ-1200 online. Any recommendations on a good replacement pump?

This is a good no-frills pump if it will fit in your chamber. From Lifeguard Aquatics-- available from Petco and several other places.
