I don't quite get you question?
If you want to remove the peat moss, you'll have to tear down the tank and simply wash out the peat moss with a hose. But make sure to save all the gunk left over in the substrate as it will help jump start your new substrate. Then add the mulm, a small handfull of peat(spread it along the bottom), and cap that with Flourite. Does that answer your question?
