Hypo ? Again?

[roggy23]

ok 3 weeks for hypo then 1 more week to raise salinty, i understand. Is it a necessity to have the fish in the QT for another week after at normal tank levels?
Hypo 3 weeks
Raise levels 1 week
normal levels 1 week<---- is this necessary?
total: 5 weeks am I correct?

The extra week at normal salinity is ideal to make sure the treatment was successful and make sure there are no other diseases.
Some people bypass this step. I have never heard a moderator give a rational explanation why this was absolutely necessary as hyposalinity should be 99% effective if done properly.
