Kim, you're sphagnum moss is finished, its holding on to more moisture then you're phal needs. The media has probably gone very acid too. Time to move into fresh new media.
After that I would choose to use some sulpher powder or some physan 20.
I would just like to say, that there is nothing wrong with using moss. I've seen many many orchids rot just aswell in bark and other media choices.
For me, moss works well coupled with bark and/or perlite.
I always combind moss with something else to keep it more opened. Sphagnum moss
alone does not work well for so many folks.
Welcome aboard kim - its nice to have you here
