Fluke-M is what you need, you can dissolve in BSDT. How many tricide neo treatment you still need to do?
At this point I feel it's better to just return all your fish back to the main pond, and treat the whole water system, since you've treat the pond recently, I would recommend some water change than do 1 dose of BSDT + Fluke-M together and don't do water change for 7 days, then water change, and do another BSDT + Fluke-M for 7 days. You can use iodine to treat the ones that is not healing well by dressing the wounds once (don't get into the eyes mouth or gills), rinse, then return to pond.
You need to kill the bugs before your fish can heal, are the fish lethargic?
