Hi,

Need help iding white fuzzy stuff on rocks? Hoping not hydroids?? Sorry pics are unclear..

Looks like the begging of green hair Algae. How long has it been like this?

Tank up for little over 3 months. Thanks!

Similar story here, my tank was set up in it's original form in December. I have this stuff all over my rock, on coral plugs, on snail shells, pretty much anywhere it can be. It's not turned green at all, just a white fuzz on everything. Watching for any ideas.

Hard to tell from the picture but look up colonial hydroids and see if that looks similar.

It doesn't seem to have the same structure to them, more like small white fuzzy hair. Too small for my camera to pick up clearly. Will try the DSLR.

I'm glad it's not. I couldn't really tell from the pictures but when I had them they made my rocks look fuzzy

Looks like hydroids of some sort, and the fact they are disappearing backs it up. They tend to come and go
