Ok, not sure what's up but wood is close to light source. Tank has been setup for a year or so but recently added driftwood and plants. Prior to the new items it had the large goldfish and some rocks from outside pond in it. Not sure about algae on back glass also but it's been there for awhile.

Thanks for the help

Anybody? I'm new to planted tanks so just curious.

It looks like some dust algae. Nothing to worry about. It is just feeding off things released by the new drift wood and should go away by itself:>
