Checked the frontier and cant find anything on the subject. Can somebody tell me what all these anoying little spines are that are spreading throughout my tank on the liverock. They are little 1/3" calcium spines that sometimes excrete a threadlike substance from the tip. Not featherdusters. They are anoying some of my corals. Is there a way to get rid of them. Is there presence a sign of something good or bad with my tank? Would appreciate some help. Thanx
