Sorry Lorraine but we did warn you this would happen. They are very sensitive to meds so if you resort to these, use half dose.
Raising the temp will make the white spot lifecycle go faster and thoroughly vacuuming the gravel will pick up the cysts.
Keep an eye on your ammonia, nitrite and nitrate levels and do water changes whenever these go up a bit. With a bit of luck you will be able to save them through the tank cycle.
Good luck
