Discovered Piece of Wood at Home. Use?

[Kaligma]

Hellos! My fiancé discovered this piece of wood while cleaning up our home and is curious if we could safely add it to our tank. I've scrubbed it and then boiled it for an hour.

We were wondering if anyone knew what it was and if it would be okay to add to the tank.

I can't remember exactly where it's from but definitely a tree in the pacific northwest.

Thank you!

Edit: Looking a bit makes me think this is in the wrong forum. Apologies if that's the case!

Is the dark part the bark? Or is there a type of poly on it? You could add it to a bucket of water and test the parameters for a few days to make sure there r no drastic swings. That’s about all the advice I can give.
Edit if that is bark I would let it season till it falls off. Also assuming it’s a type of hardwood.

It is bark, thank you! Makes sense to test parameters in its own waters. Much appreciation.
