Pump for my bubble magus NAC 3

[707 Reefer]

I'm looking to replace the pump for my bm nac3 and don't know what type to look for. Are there certain ones that will only work for this skimmer? It seems to me that when I top off the water level, the pump stops producing bubbles. After a few days when my water evaporates, the bubbles in the skimmer return. This problem didn't happen in the past. Any ideas? Could I replace the pump on the skimmer or do I have to get a new unit?

replace the pump would probally better it also recommends 8"-10" of water. they also recommend using atman aquabee or eheim pumps but im sure most any pump will work
