Skimmer help
 

I need HeLP lol. I bought a used skimmer last night that was working, unfortunately I didn't get it into my new tank until today. My problem is that I can't get it to work or bubble. I can hear the motor running but not sucking water or bubbling. I tried to "prime" it by pouring tank water in it like I did the 5 stage hang on I have on the tank to but it didnt work. Any advice to get it going? It's a hng on skimmer.

Got it going.
