just curious if anyone here who has a nano has rubble in the back chambers? i have had a few pieces back there since i set up tank. i am starting to wonder if these 3-4 pieces of rubble have any use/importance. i see a bunch of detrius back there. i am thinking about cleaning back chamber and getting rid of those pieces. the pieces are around 2-3 ".
