In this video (at about 8:40 ish), , they state that copper becomes more toxic as the salinity drops. Does anyone know at what salinity level that one would expect or might expect issues with copper toxicity in some fish?

My misunderstanding, thanks for the correction!That isn't true with copper power or coppersafe (coppersafe can actually be used in FW). I don't know where Cupramine stands.
This idea stems from using ionic copper, back in the day. It is toxic in soft, acidic water, with low alkalinity, it isn't the salinity per-se that makes it less toxic, just that higher salinity water also has higher alkalinity.
My reason for not using hypo along with copper is that it increases the stress on the fish, plus hypo has been shown to increase the chance of Uronema, so that is an added risk.
