Reefing newb
I was cleaning out my powerheads the other day, and one of my newer koralia 2's would not work upon resubmerging it in the tank. I took it back out and tried to make sure everything was put back together correctly and it is, no broken parts. I even used my ohm meter to compare the impedence of it compared to my other koralia 2's and it was the same. However, it will not spin at all upon plugging it in. What should I do?
