While that plant is in moss, you need to water less frequently for sure. You see, the moss acts like a sponge and holds the water, and lots of it, on the roots. Phals like to have their roots in pockets of air and moist substrate. They like light on their roots as they photosynthesize through them.
The moss basically suffocates the roots when it's sopping wet, and it stays fairly wet for a long period.
I would water from the top in measured doses. Run water slowly in small amounts. The moss on the top will absorb water and be very wet, but you may not have any water further down. It's a tricky situation. Water until some water starts to come from the bottom of the pot, then stop.
Repot the plant as soon as you get the nerve to do so. I repot as soon as I get them. Phals in bloom generally won't miss a beat and continue to keep the blooms.
There is a lot of instruction in the repotting subforum on how to repot and what to do with the bad root, how to identify them etc. Go have a good read!
