I would agree Scott, if you are getting stable, a diatom filter is useless. You are going to have a diatom bloom most times
that you dick with your sandbed or make major changes to something, but normally there should be imperceptible amounts
in the water column. I would think that diatoms are excellent food. Fanworms gotta eat, too. If the way the filter works
is giving you hair algae, haha, pull that junk.
