New thread...

I'm getting ready to place a supply order and was needing some advice on this repotting plan before I place it, incase there's something else I need to order I'm not aware of.

4 of the orchids I have right now were given to me from a family member. None have ever been repotted and I have a small mold/fungus issue going on, I also noticed some small (like tiny, tiny) critters today in two of them. My plan is to repot or mount everything that I have and do a physan 20 1hr soak on all of them at the 1 1/2tsp per gallon ratio in the process. After the soak then repot/mount I was going to wait a week before watering and just spritz them in the meantime. Is there anything else I need to consider? Do I need to flush them after the physan 20 soak? l also have some new orchids coming in the next week so I planned on doing this process to my existing guys + the new guys at the same time, per BD's original reply to the quarantine question. My concerns are 1. My 2 Miltoniopsis. I haven't decided how to repot them and the physan20 soak on them scares me. 2. I have 5 plants in bloom right now so it's not the optimal time to repot but they all need it. 2 of those bloomers are my Miltoniopsis and one of them is amazing right now, probably has 20+ open flowers. Thoughts? And thanks in advance for any help.

I took a look at spider mites and mealy bugs and these are neither. They are super small, like 1/4 of a pin head size. I would've missed them except they were on a white background.
