loud Powerhead???

I didn't I just noticed a loud buzzing sound coming from it and discovered that it was pulling water instead of pushing it and played with it a bit until I got it spinning correctly.

See this is why I love you guys, I just remembered that last night when I feed the tank, it seemed like the food was getting sucked toward the loud powerhead, I thought it was just the draw towards the back, but it could have been what you are discribing. I will play around with it later, thanks for all the ideas.
