A little peat goes a long way. It won't take much(peat is VERY acidic) to lower the PH and keep it there. You may tinge your water a light brown color, but you could probably live with that.
What kind of de-chlorinator are you using? Does it remove Chloramine? If not, get some that does, and try testing your water again(for the ammonia), after you treat it. If your water supply has 1 PPM ammonia in it allready going to be harder. I would try a de-chlorinator that also removes chloramine.
