That should be done along with regular partial water changes, which I do 
weekly, even when I am setting up a new tank.  Not because it needs it, just 
to get myself into the habit.

Peat will lower pH and hardness simultaneously, and brown the water in the 
process.  Is there are reason for doing so in your tank.  If your fish prefer 
softer, or more acidic, water, sure.  Otherwise, don't mess with anything you 
don't need to.

Just wait it out.
