Probably not. They will tolerate the drop way better that the opposite.

To big of a difference.

Can't you raise the QT to the same salinity then drop if back slowly if you need it that low?

+1 Exactly. Going from 1.021 to 1.025 would be a problem, but not so much when you lower salinity on a fish.

1.021 to 1.025 should also not be a problem for fish.

Disagree... Some fish may tolerate it, but overall too much risk of osmotic shock raising that much all at once.

I have yet to find a fish that can't handle going straight from 1.021 to 1.025. And I have done this as the final step for going back to normal salinity with every single fish I treated in hyposalinity.
Below 1,020 you should do it slower and the greatest risk is with going from 1.009 to 1.016 because that is the range where going too fast could cause kidney damage.

My general rule is .002 every few minutes for raising salinity, a little looser for dropping it, but I prefer to go a little slow. Never had a problem doing that.
