Kiwi Posted December 1, 2013 Share Posted December 1, 2013 I have no Idea, what this white feathers (polyps?) are….. (1-2mm large) are they harmful? Link to comment
Mazzy21 Posted December 2, 2013 Share Posted December 2, 2013 I think it's just dead stuff - most likely dead algea. I have that 'fuzz' on a couple pieces of new LR I bought too but it's flapping in the current and appears to just be deteriorating. I'm not an expert by any means but I really think it's just 'gunk'.

Rollermonkey Posted December 2, 2013 Share Posted December 2, 2013 Hard to be sure... Google 'colonial hydroids' see if it looks like what you have. Link to comment
Kiwi Posted December 2, 2013 Author Share Posted December 2, 2013 They seem to be some kind of hydroids…they retract when being touched…. but I have read there are some, that are harmful…. Link to comment
