I came home from work the other day was looking at my tank and noticed little black dots everywhere on just my driftwood. There's at least a hundred of them. Over the last couple of days they haven't got bigger or anything so I'm not sure if it's algae or what.. any thought?

Also here's a picture of my gbr just because she was looking good excuse how blurry the picture is, she wouldn't stay still lol

If its a new piece of wood to the aquarium, it could be Tannin staining.
It can alter PH so keep an eye on that. Over time, when all the tannins seep out, the PH should be stable,
