Is this type pot and this orchid bark good?

Wow! Y'all are incredible, I can't thank you enough for all of your help in saving this plant. So, here is the pot I ended up with, which actually ended up being smaller than I expected but if only the roots fitting is the idea then maybe it'll work? What are your thoughts on this pot? And I ended up using that mix I bought that was the bark, charcoal, pearlite mix. Since this plant and the pot are so small, and this medium is so big, I wasn't really sure what exactly to do but I got some chunky pieces of the bark, a couple pieces of charcoal and a couple pieces of pearlite and fit them into the void in the center of the roots that I had dug all of the clumped up old stuff out of, put a few pieces or bark into the bottom of the pot, stuck the roots with the bark stuffed in the middle in there, and then fit some more bark in the large voids to sorta fill it in. Also, to keep it warmer, I really don't have any other room in my house with the correct lighting, so I have put a gallon bag over it as a tent and I stuck a thermometer that also measures humidity under there to so I can monitor everything, the humidity has been staying between 60-70%. I also have been leaving the laundry room door open so that it stays as warm as the rest of the house, this has been keeping the temp no lower than 68 at night and around 72-74 during the day, is this okay or still to cold? And the most exciting news, a beautiful little new leaf has opened up in the center! So, what did I do right? What did I do wrong? What do I still need to do? Lol Also, should I still soak it? Which leads me to another question, we have well water, and it's very hard and the ph bounces all over the place, is this okay for orchids? I also have reverse osmosis city water I get from the city, would that be better for it? Thanks again for everything and hope you are all having a wonderful Thanksgiving!
