I agree, I think it has something to do with the algae I have on my glass. I cleaned it off and it seemed to be holding, but then I decided to use the clips included. For my other three powerheads that wouldn't work, because they are under my eurobracing, but this one is on my overflow so it worked well.
Do you guys use those little thingies that spread the water out like a fan? I put one on, I hadn't noticed them before, but it seems to reduce water flow significantly. And it's ugly.
