What is the best way to get rid of the mulm that accumulates in heavily 
planted tanks besides periodic light gravel vacuuming on the surface of the gravel, 
taking care so as not to disturb the roots of the plants?  Are there any 
other ways to get rid of the mulm that inevitably accumulates in our planted tanks 
besides that?
