OK so I changed my filter pads in my fx5 today and was doing a water change. I plugged my fx5 back up it started working as normal for about 20 minutes then it just went silent. now i know it stops to get all the air out but this isn't one of those kind of stops. Any idea what the problem could be? I made sure enuff water was in it ande have plugged it back in several times it doent even make the lil hummm sound thanks..oh and i only had it 5 months brand new
