Welcome to the board! Phals are the easiest to grow (most varieties) and one of the best ways to get started with orchids. You probably didn't need to change out the moss right away, but as I've learned from experience it is almost mandatory to change it once per year. It may look fine after 12 months, but the pH balance is off by then and not very friendly for the plant. I've made this mistake 3 times (the charm), so from now on I change after a year and then switch to finely chopped bark.
