Will that by chance bring the plant back? Can you remind me about the listerine and peroxide?

since the humidity in your environment is enough to sustain the plant, refrain from watering regularly....make sure to let it dry for half a day before watering....moist and warm can be bacteria and fungi haven....the telltale signs are the algae and mold that forms on the media mix....

spray the plant....with hydrogen peroxide you get from the local pharmacy and alternate it with brown listerine(the original not the blue one)

it will not set it back since it is still in growing mode....you can unpot it and clean the roots....Catasetinae have robust roots that is not like the fine roots of Dendrobium that will sulk and not flower if disturbed....

No mold. But i will spray w yellow listerine for sure. And change into fresh media.

All i have is fine mix by Black gold i can add lava rock to that. Would that be okay otherwise i will jave to special order something else.

Should i go ahead and spray my others down as a preventative.

The old school listerine is not diluted correct? Sprayed directly on the plant and media

try Euplusia's sawdust mix....60% sawdust, 40% clay shards and a spoonful of dolomite rock powder....I have used it last spring when new growths needed repotting....it is really working well for my Catasetinae plants

Okay i will look into it. I dont have sawdust readily available and will still need to special order some.

I got my sawdust off of Ebay. Comes in bags there that are fairly inexpensive. I changed mine over too. They are doing great!

Wonderful. Uh what kind is best? Because i am clueless.

It now sits in front of an open window in my bathroom. It gets the humidity and the sun w the air flow. So i am so praying it will bounce back. How long do i need to do the alternates of Hydrogen Peroxide and listerine?

Is western red cedar okay? I know certain ones have tannin's that are bad for orchids

I think mine is Maple dust. I tried to avoid anything like Pine or treated woods.
I had a bulb that did the same thing as yours did. I just watched it and it ultimately gave me two Keikis. Once they had good roots, I cut the whole bulb off with a sterile scalpel and laid it down into the sawdust mixture. They are growing quite happily now and the mother plant is doing fine as well. I did treat the plant with thiomyl since it is a systemic. There have been no signs of pathology since. It got two doses, one week apart.

Oh great I can get that for like 10.00! Hurray! Now clay chips/shards? Is that like some of my busted pots I have laying around to let the spiders live in?

Kindra,
Can you describe the conditions that you're growing these plants in? Things like daytime temp hi/low, typical RH and watering frequency. Light levels are also required and maybe some pics of your grow area and of the plants themselves.

Rot during the active part of the growing cycle in these guys is very unusual, so I'm thinking your problems are cultural.
