Needs Cleaning

I have an aquarium that has a few tropical fish in it.  Ever so often the filter system builds up sludge and I have to take it apart and clean out the mess.  I hear it making a noise at me, which is telling me the small turbine inside it is laboring to work properly.  This means it's time to do the cleaning job, which takes a few minutes of washing the filters, removing the turbine and cleaning out the area it's located in so it can turn without restriction.  I'm going to make an effort to get this done today, without procrastination.
