Phal with sponge growth on roots!

[Apricot]

Hello all.

I recently received my first phal for my birthday two saturdays ago. I was ecstatic and excited and all I want in the world is for her to be happy. She came to me with blooms and I have repotted her in a bark mix. For the last week or so I noticed that her leaves have gotten floppier so I decided to water her at least once a day. (Whenever the aerial roots looked gray/white) However, when I checked on her this morning I saw some sponge like growth on her roots! There were about 5-6 areas with the growth so I panicked and snipped them all off! (With a pair of scissors I cleaned with alcohol) I transferred her out of the pot she was in to a disinfected vase with the left over roots exposed. I'm wondering if I should remove even more of the yellowing roots and if I should do more for her. Any input or advice is very welcome.

Here are some photos taken by my phone. One of them is how I have her set up now. A few of the roots are green and many are yellow. I read online that as long the roots are not mushy or dried looking, I should leave them on. What do you think? And the sponge thing that was growing on the root I left in the bark mix.





Thank you!!
