I realize that your hoping to prevent an Ich outbreak in your tank ( and that thinking is very good) , but the 90 degrees temperature is going to do more harm than good. Stressing the fish unnecessarily. Stress of fish is what we dont want- it opens the fish up to many other diseases besides Ich- primarily bacterial infections.
I would turn down the heat to 80 degrees and if Ich parasite is present it will show itself within 3 days at this temperature. The parasites life-cycle is very rapid, completing the entire cycle within 5-7 days ( again, at this temperature).
The best thing you can do while fish in quarantine is to keep water very,very clean, feed high quality foods, and watch.
I am sure that what you are seeing in water column is harmless. The harmful worms/nematodes etc... are primarily not visible to naked eye. Might be planaria, which feeds on excess uneaten food and occurs in tanks that are not routinely maintained: water changes, filter cleanings, substrate vacuuming.
Internal worms like flatworms will usually fall from the fish onto the gravel, and can be seen, but do not float around in mass in water column. External worms, like thorny headed worms or anchor worms will be attached to the fish.
