I pulled a lot of the sphag away from the plant to check the roots. There are strong roots in the medium. So I removed a lot of the moist sphag and replaced with soil.
I also used a thin stake to aerate the pot by gently poking the stake into the medium. I'll let it be (watering ) for a bit and see how things turn out. But keeping an eye on the new ariel roots. When I have watered it, the water does run through it and out of the base.

PJG,
I hope you did not use potting soil. It is way too heavy a potting mix for Phals., which are actually epiphytes living in nature on trees. (hence all your "sexy" aerial roots looking for a new foothold!) A medium, or equal parts medium and fine rinsed fir bark, mixed with some perlite would serve you better.

Soil? It's not good for orchids. You may want to try bark or other mediums. I have mine in bark and S/H. I used soil when I first started this orchid hobby and killed them.
