Aquaclear 110 filter?

[SeriouslyaWhoCaresm]

Ok so I have a 55 gallon saltwater fish tank and I am trying to convert it into a freshwater fish tank. I have the Aquaclear 110 filter...can somebody tell me how to clean it? I threw away the manual.....

thanks in advance to anybody that answers...seriously

P.S also if you know how to clean some feather dusters that have grown and r really hard to take off..
Thanks Again
