Cleaning some of the biomedia would do basically nothing. The bacteria that live in the biomedia are what turn ammonia into nitrite, then nitrate. So you may get a bit of an ammonia spike if you clean the biomedia, but not likely, since the bacteria that's in the rest of the media would quickly recolonize the new media.
