White Puffy Stuff (Fungus?) On Mopani Wood In Tank

[eaglesaquarium]

Well, that's the problem. I noticed a whitish puffy substance on my mopani wood in my tank today. I have two pieces of mopani, but only one has the stuff on it. What can I do to eliminate it. It comes off easily, so obviously I could just remove it manually and hope it does return, but I'd rather find out what it is and what I can do to make sure it doesn't come back. Sorry for the quality of the pic, I'm not a very good photographer!

Those are air bubbles trapped inside the stuff...

Should I dip it into some sort of a chlorine solution? What potential hazards am I looking at with this?



There are no fish in the tank currently, but the rescues mentioned in the sig are coming tomorrow!!! Besides removing the wood from my tank, what else can I do?!

I would like to know as well, I just put a few pieces of Cholla wood in my aquariums as well and noticed a few days after that it developed the same type of stuff on it..At first I thought it might just be food that got caught in it, because it has holes in it, but then it happened on a few other pieces too..Then yesterday I noticed it had disappeared on the piece I saw it on originally..doesn't seem to harm the fish thus far though..And also in the tank that I have a pleco in it hasn't showed up on any of that wood??

I posted the question here also, and Ian answered it.

It sounds fine.
