How Safe Is Decor Used From The Wild?

[PYRU]

If there’s a bunch of bugs on the piece I usually pour boiling water over top before blasting with hose/pressure washer. Anything I miss becomes a nice snack for the fish in the tank.

I forgot about that. I usually scrape off or pressure wash the wood worm stuff.

I use wood and field rock in most of my tanks. No negative effects. Use percussions mentioned above.
Be sure nothing comes from an area treated with pesticides. And no sap woods(pine being a big one).

I like using big thick dried out tree roots. No bark to peal/break off.

Walnut is toxic and so is eucalyptus, most other hardwood is safe.
