There is some manzanita branches which I soaked for about 2 weeks and didn't show any sign of this. Also it is not on the wood, but on the substrate/rocks.
I hope you are right, in the mean time I hope you are right. As I am one week into fish less cycling the tank I am running ammonia at 4ppm (added from bottle) and currently reading 0 ppm nitrites and 0-1 ppm nitrates.
I will keep dosing excel every other day to see if that helps and I'll vacuum it up if it gets too nasty.
Wherever you go, there you are.
