Protein skimmer stopped working

[Chris Vo]

Can anyone please advise?! I have a three month old SCA-301 skimmer and I unplugged it while feeding my corals earlier this morning. When I plugged it back in, no response from the pump. Apparently it comes with an atman 1100 pump needle impeller pump (whatever that means). Any guidance would be welcomed and appreciated!

Check to see if the impeller housing is crudded up with calcium deposits. You will need to take the pump apart to see. Deposits have ceased up my pumps many times. If so, you can soak them in vinegar for a while then scrub it clean. I use Crystal Clear Aquatics Zap Cal.

I had that skimmer, the pump does that every now and then.

You can tap/gently smack the skimmer or plug and unplug until the propeller spins again.

Its not dead, just stuck.
