I get the churning sound sometimes too after cleaning. It's just trapped air. I sometimes power on and off the filter. I also use the push button prime to help blast out any trapped air. It should go away on it's own within a day.
After making a mess in my tank it's usually clear by the next day. I love my filter. It's so easy to work on and does a great job polishing my water.
