First make sure you really do have 2 ppm of ammonia in the tap water. As far as I can find by googling, 0.2 ppm is the accepted limit for ammonia/ammonium in drinking water.
You don't need to cycle planted tanks anyway. Just plant heavily, with stem plants, fill the tank, and wait a week or two before adding a few fish. Add a few more each week until you reach the fish loading you want. With Aquasoil it is recommended that you do big water changes a couple of times a week for a few weeks to get rid of excessive leached ammonia from the substrate.
