Slightly Lower Salinity With Copper??

[Justdrew]

I am getting ready to treat fish with Cupramine for a Crypto outbreak. I understand that lower SG is less stressful on fish, easier to osmoregulate. My question is, is it better for the fish to be in slightly lower SG, or leave them in the same SG as the DT. I run the DT at 1.026.

Thanks
Drew

you can run the salinity a little lower like 1.021 but not too low. I'm currently doing the same thing with an emperor in qt.
