I used zinc powder, works great. Second choice is thin zinc metal, but powder reacts like "now".
Got used to this zinc and how it reacts many years ago.
EDIT: You have to use it in additions as the reaction can be too much and foam over. It still took time and stirring but works well.
Copper is slow to dissolve. But I am thinking it will work. Slow.
EDIT: It is HCL Bleach. Don't know reaction of copper. But HCL needs bubbling air like AP solution.
The chlorine made from the bleach gets used up thats why you have to keep adding it. Also when heated even by the sun drives out the chlorine from the liquid.
