Help, need small refugium pump

[old salt reefer]

I have a Figi Cube HOB medium refugium and the pump is putting electricity into the water. What a shock for me, but doesn't seem to both fish. Sucks that it's only 4 months old. But I need to find a replacement, which I'm having some trouble doing. Figi Cube doesn't have a replacement pump on their website but I have emailed them. In the meantime I need a pump. Most important is the inlet has to be able to fit a 5/8 inner diameter hose on it and the pump can't be more than 2 inches wide. I'm going to look at a powerhead tomorrow and see if I can make it work- Aquaclear 20 or 30 or a Imagitarium aquarium power 12 watt is what I've looked at so far. Anyways here are some pictures of the pump any suggestions on a replacement. Thanks for any help.

Never mind, answered my own question. Got a Marineland 600 powerhead, had it in and up and running in 10 minutes. Works like a charm.
Funny had decided on the aquaclear 30 was getting it at Petco. Their website showed in stock at 3 stores near me at 1 this morning. Got up checked website again and out of stock at all 3, imagine that. So looked at Pet supply plus and came up with the Marineland powerhead. As well as it fits I think the dear Lord was watching over me.
