The Odd One

It’s a dark black color

If it is biofilm then that would be great since it’s going in my shrimp breeding tank. Thank you😊

So I was wondering if anybody knew why my driftwood shed its skin.( I don’t know if it was even the bark it shed) and then turned this really ugly black color. I had it soaking in a tub outside for the past month to get the tannins out and it’s been really hot, soI don’t know if that has something to with it too. If anybody knows what the problems is thanks in advanced!😊
