Problem pump

[fishtankrob]

I have a little giant pump. I did a water change and when i turned it back on it made some noise. i was not pumping near the volume it did before. what went wrong, i didnt do anything to it. any help would be great.

well you should take it apart and see if any thing got in there and try cleanin the inside out, that should get you back up to speed,
