Peat would probably work better than indian almond, but you'd have to tear up the tank to put it down under the substrate.
I always try to get inhabitants that suit my water, rather than making my water suit the inhabitants, it's MUCH easier.
If you are bound and determined to play with PH I'd look at using reverse osmosis water. The PH should be around 7.0, and if you do feel the need to buffer the water will change PH much more readily because it's not full of ions and minerals.
