Brassia rex x Brassia longisima: the sickies

We got this plant bare root, for what we thought was a good deal, from the local guy who grows tons of orchids and has a sale at his home greenhouses every year. We were really excited about it because a Brassia rex had been on our list of things we would like to have. It was three divisions with some good new growths. We potted them all into the same large clay azalea pot with a lot of Styrofoam in the bottom and our standard bark mix. We watered once per week, and sprayed the top when it started to look dry to encourage any new roots. There had been some spots on the some of the leaves when we got it, but the leaves fairly rapidly turned yellow and fell off. Basically it had a fungus or something and most of the plant died. The pseudobulbs started to rot and get all mushy. This all happened over the course of about a month. We only have a little bit of the plant left. The same thing happened to a friend who had also bought one of these at the same sale. We repotted it into a large rehab chamber- a 6" plastic pot with lots of holes in it filled with Styrofoam peanuts in the bottom and sphagnum moss. There's only two pseudobulbs left of the original 8 or so, and 2 growths to go with them. So far it seems as if these sections might make it, but time will tell. We haven't ever treated for fungus or bacterial infections before, so we didn't know what types of products to use or where to get the right things for orchids. We had never had this kind of disease problem before and were kind of mad that we had been sold bum plants. Oh well, hopefully these pieces that are left will make it because we were really excited about having that plant.
