I got a new anubias and tied it to driftwood now the stem is turning brown. Is it dying or getting used to my water parameters.

Yes. It looks like it is rotting. If the rhizome is rotting you need to cut away all the rot to give the rest a chance.

How long have you had the Anubias plant?
I agree with trimming the bad roots and yes plant is adjusting to it's new environment.
