i used to have a similar problem when i ran pot scrubbies in all three baskets. it would shoot out bubbles and gurgle all the time. i finally got fed up and switched to ceramic media in all three baskets and its been perfect ever since and it flows like crazy.
when i was having problems, i also took the pump off, but there was nothing there. i think the problem could be with your pads. how about the foam around it? has it been cleaned lately?
