Questionable driftwood?...

So, I had driftwood in my tank that I purchased from my LFS about a year ago.
I took a break from fishkeeping and all the water evaporated. Then, a bunch of white mold-like thing grew on everything especially the driftwood.

I washed my tank out with hot water and a sponge and every growth is gone. I was wondering if I should use this piece of driftwood or not.

Is my tank safe for fish?

 

Sure. Just boil it and it should be fine.

 

A white film is typical with new driftwood!

 

give it a boil, or if its too big for a pot I have heard that the sani cycle on a dishwasher does a good job too, just NO SOAP. The film is to be expected, I have this happen all the time currently as I'm adding driftwood to a lot of tanks. My pleco didn't seem to object to it much at all, other than that it kinda fell off on its own and I vac'd it out,.

 

Some snails will eat the film as well.
