Weird algae growth on driftwood
I have had my new 20 gal planted tank up for about a month now and im starting to get this weird clear algae slime growing on my driftwood. My tanks is completely algae free otherwise except on the wood. I cleaned it with hot when I first put it in and again yesterday when I did my first trim but it's still there. Any ideas what this is and how to get rid of it?
