I guess it is some kind of Bacterial stuff, mine just disappeared after some time. I'm currently cycling a new tank , and have this fuzz since day 2
I did a water change yesterday and used a razor on the back glass where it was the worst it almost looked like tree fluff with a tiny black root base at the end. it doesn't seem to be bothering my corals which is a good thing. this popped up about a week or so ago and was at it's worse just the other day. aprox how long did it take to go away for you?

I seem to struggle with this same issue every time I start a new tank. It hasn't ever gotten as wide spread as yours appears to be, but instead pops up in small patches on the rocks in 2 or 3 areas. I have yet to find a definitive ID or solution to it and it always seems to go away on it's own as quickly as it appeared. It also seems to appear anywhere from 3 to 6 months after setting up the tank, usually soon after the initial cycle.

3 months ago I bought and setup a new all-in-one nano tank (JBJ Nano-Cube 29g). I set it up and started the cycle as I always do, using Bio-spira, live sand and rock and a clown fish that I've had for years and always use for this. And sure enough, two days ago the fuzzy cotton-like "fungus" has appeared. To me, it strongly appears like a fungus. This time, I'm just going to let it run it's course and not drive myself nuts trying to intervene. I've experienced this 4 other times and it always goes away on it's own.

I am a veterinarian and we use a lab to send samples to for ID. Today I scraped off 4 different samples and put them in various culture dishes and one in a sterile non-cultured test tube. I will send it off today for identification and sensitivity test. As soon as I have the results I will post them here. It will be nice to have an answer regardless!

Happy reefing everyone!
did you ever find out??
