Posting for a friend, since we both can’t figure out why his tank has all of his new driftwood covered in this white algae or mold. No fish are in there, and it’s currently cycling, but it almost feels like slime but a tad harder to pull off (you can’t just use the water current to have it tear pieces off).
I searched online and it’s hit or miss with this either being common or something else. Any advice?
