Sounds like you either have an fungus problem in the tank, or a lot of old sludge in the bottom. The pre-filters can be rinsed out if it is getting plugged up a lot. Just flush water through it the opposite way, and then dry it out really good.
If this keeps up and doesn't seem to stop, you may want to clean your tank out.
