These little sprouts of algae just began to appear in my tank yesterday. They're all over the sand bed, and beginning to appear on my rocks and tank glass. They're only about a millimeter tall at this point. Whatever it is, I want to nip it in the bud before it becomes a real problem. Can anyone identify and let me know how to deal with it?
BTW, my tank has perfect levels - no nitrates or phosphates (API tests). I have a small CUC consisting of just a bunch of small assorted reef safe hermits, a few peppermints and a pistol. Nothing really algae specific because until now I haven't had any algae issues. Tank is about 6 months old now.
