If it were my plant, I would re-pot it in small fir bark, 60%, perlite, 20 %, and small chunks of charcoal, 20%. Soak all of this in water overnight. Next morning, put a small layer of lava rocks into plastic pot then put orchid into the pot. Your pot should be the same size or slightly bigger, but with slits on the side and holes on the bottom. Fill in pot with wet medium around the orchids' roots. ...DO NOT water for seven to ten days.
