asm skimmer pump slow trickle?

[jukboxx]

hello fellow reefers, my asm skimmer pump is not working right, very little pressure going through it, i didnt know if there is something i could do to fix it or if i need to be looking for another one, it is the sedra 5000 (500gph) i noticed the other day that it was not on but when i blew through the air line it started working, this lasted about a week or so then it stoped again. i took it out and ran some warm tap water through it and now i am at a stand still not sure what to do. if anyone has had or knows how to fix please give me some advice. even if it is a good place to get a replacement pump (reasonable) thanks guys

I would pull it out and soak it in vinegar for 24hrs. Take the impeller out and soak the shaft and everything apart. Then look to see if the air injection hole is clogged. If that doesn't work you'll need a new pump.
