Good to know. I'll start removing tomorrow during my water change.  So far I only see one clump, but I imagine more are to come. 
 
I think I will try a mesh bag filled with GFO. Obviously it won't be as effective as a reactor, however I'm guessing it's better than nothing.  I don't have the heart to plumb in reactors, nor do I have the room.
