Hi All and Merry Christmas!

I am looking to add some discus to my fish collection this holiday but am worried about internal parasites due to the vendors feeding live stuff.
I've looked into various treatments like levamisole.
I know the typical dosing frequency is Day 1, Day 7 and Day 21.

However, my concern is temperature.
I understand that parasites have a faster lifecycle and reproduction in higher temperatures so am just wondering what
the right temperature is for using levamisole to treat roundworms? (most i've read is people using 82-84F).

Thanks and Happy holidays!
