I've been growing out some Chaeto in the fuge section of my sump. Seems to be growing and doing well, but it just sits on the bottom of the fuge. I've seen videos of other folks who have this floating ball slowly rotating. Is it just that I have low flow through my sump or is there some magic trick here?
