white/grey thick cotton like substance.


I've been noticing this stuff on my driftwood, but now is moved onto the stems/stalks of plants. It is white/light grey, and looks like a cloud surround plant or stuck to driftwood. Any idea what it is? I have brushed it off dw before, but it comes back quick. Have done some googling and it may be a fungus, or just part of tank life that will take care of itself. Not sure. Pics. Hazy, as camera would focus on whatever is closest, cant focus manually.

did you cure the driftwood before adding it to the tank?
Here's a pic of my old driftwood: http://imgur.com/lYShu
Does it look like that?
I left my tank alone for about 3 days for vacation and that stuff just "disappeared"
I had bacopa, java moss, and cherry shrimp. I was also running a HOB.
