My QT protocol goes like this:
Day 1 - TTM phase 1
Day 4 - TTM phase 2 and dose Prazipro
Day 7 - TTM phase 3
Day 10 - TTM phase 4 and dose Prazipro
Day 13 - Move to QT tank for 2- 4 weeks observation.
Medicate as needed and maybe stay in QT longer.
I started this after a Purple Tang brought in Ich that wiped out $600 worth of fish.
Since then, I have lost fish in QT, but not a single one in my displays.
