Eleonora just grow it as is. If you are new to orchids, it might be best if you don't disturb it again. I am just trying to provide you with as much good information as I can.
A BIG thing you have going for you is that Phalaenopsis respond very well to repotting! Very well! They typically produce new roots within 4-6 weeks after repotting. Sometimes it could be more like 8 weeks.
Just keep it out of really bright light and make your regular waterings. It will do fine!! I promise.
I have been growing for a lot of years now and I make it a habit of repotting my orchids as soon as I buy them. I want them in my preferred media ASAP and when I repot, I get to see what the root system looks like. That is very important to me. The huge unknown, the health of the roots, becomes known to me right away.
