About a month ago I took apart all of my pumps and powerheads and gave them a good cleaning. Since then one of my koralias has been making a clicking sound. I've taken the impeller out several times and made sure it was in there right(I believe it is, kinda hard to not put it in right) but that doesnt seem to help. If I unplug it and plug it back in its quiet again for a while but starts clicking again after an hour or so. This PH is about a year old. i did the same thing to my K3 and it has no issues... quiet as the day I got it. Has anyone had this problem and what did you do to fix it?
