Curpamine is the best copper. However, no copper should be used in an aquarium that contains rock or substrate. You are going to have a difficult time maintaining a constant copper level in a tank that has rock or substrate. You should be testing the copper level twice a day and adjusting the dose as needed.
There simply isn't a reason to combine copper and hypo. Hyposalinity alone will cure ich without using harsh chemicals or heavy metals.
The pH tends to fall in diluted saltwater so you need to check the pH daily. Copper becomes more toxic as the pH falls. Combine the two together and the copper can kill the fish when the pH falls.
