I recently started to notice, these white spiral things growing on my tank glass and on my live rock. They are about 1 mm in diameter, some are bigger and some are smaller. I also noticed what looked like "a white cloud" coming out of it. Sort of looks like a feather duster. Are they good or bad? Should i scrape them off of everythign? Any medicine i can use to get them off if it is needed. Or should i just leave them on there???
