Tiny, fuzzy, cone things on wall/glass - good/bad?

[ecumike]

Anyone know what this is, and if it's good or bad??
I have a ton of them growing in my overflow and sump now. They are stationary, attached to the wall/glass, cone is fuzzy/furry looking, and looks like a tiny feather on top . They are only about 1/5 of an inch tall....

And also, is there anything in particular that causes thses things? (like bad h2o/phosphate/salinity/additives)

i have some too. are they whitish transparent? mine are. all over in my overflow (external) and my sump and refugium. all over the snails in the refugium too.

i am sure they are filter feeders of some sort but not sure if good or bad...i think they are good but don't konw

jdeets, i have some of those too but mine are all white. what are they?!

 

[jdeets]

These are scypha sponges, Scypha sp. They are little filter feeders and are harmless.

Is that a sponge? I have several white ones and had just assumed they were sponges.

Naw, that's not what they look like.

Lunchbucket got it... they're whitish transparent. And they are starting to show up in the tank now also.

I'll try and take a pic. of them tonite and post it here.
