Copper in low salinity

[Tflow256]

I picked up a fat head anthias last night and got it in a QT. Noticed a couple spots on it so I wanna start copper treatment asap. Normally I wait till I bring the salinity level up to 1.025 (I match my QT to the salinity of where I get the fish..in this case 1.021). Id rather not wait the week or two that I slowly raise the salinity up but I'm also told it's better to use copper at the 1.024-1.026 range as its more toxic at lower ranges. I use cupramine, any suggestions as to what level to keep copper when salinity is 1.021?? Thanks in advance!!

You do not need a week or two to raise the salinity from 1.021 to 1.024-1.025.
I would do it in about 6-7 hours.

You can treat with Cupramine @ 1.021. You just don't ever wanna do it under true hypo conditions (1.009).
