ID white fuzz please

basile · Dec 29, 2014

Got this white fuzz growing on my rrock in the dark zone for now. I read in some place it goes in the lit zone as well. A bit worried.

My system is a high nutrient one and i dose every hours for my NPS zone, gorgonians, and sponges.

So far nothing really has been affected but , well some of my zooz have receeded but i don't see any fuzz even near their location which is in full light.

Anyway anybody has an idea of what this is and if its harmfull and how to get rid of it IF... Thanks for your time.

Oh this i know is not harmfull , filter feeders but what is it again can't remember.

maybe sponge not really sure, kinda funky, never seen fuzz like that.. maybe some kind of bacterial or fungal growth.

the spirals are spirorbid worms.
