Hi! Looking for any constructive feedback, after nearly killing my favorite phal in my first re-pot with store bought bark media, which combined with my zealous watering resulted in total root rot

I decided to try something altogether different, repotting into Leca with styrofoam and just a hint of new zealand sphagnum moss, in pots I hyper-aerated by making holes with a hot nail. Does anyone have any experience with this type of mix/growing in net pots? Hoping I did the right thing for my beauties.
