Mini Pump 106 makes occasional buzzing sound?

[happyclam]

Hello,

I have been using a Mini pump 106 in my small 3 gallon reef and it has been great. The pump is very quiet most of the time, though occasionally throughout the day it will make loud 'buzz' noise for about 15 seconds. It generally stops quickly, though sometimes it persists longer. Unplugging the pump and then restarting it generally solves the problem in this case. Is this anything to worry about?

This will generally mean air is in the pump or the shaft is loose. I would open it and push the shaft in, be very careful, the shaft is smaller than a finishing nail and could be so loose it falls out so do this over a table where you can retrieve it.

Ok I will try that. Thank you!
