Cooking rock and copper

[EL_Perron]

I tried searching here and the google webs and I couldn't find anything.

If I cook dry rock with bleach and of course follow the process to remove bleach, would any copper be removed?

I asked, because I am looking for buy some true old school live rock, but without knowing the history of copper usage, I worry that if copper was ever used, that I would run into issues in the future.

Bleach won't remove the copper. You could test the water that the live rock is in for copper using a hanna checker.

From my understanding, all the checkers for our hobby are not the best and may give a false sense of if it is safe or not.

I had a similar occurrence and actually just did the test with my Hanna (use it for checking the QT tank). The rock is cooking in a 60 gallon barrel w/ bleach. I tested a sample from last week, it was .06, today's sample was .10 and I double checked the hose I used to fill it, 0.00. So I am in the same boat. I also feel scammed by the person I got it from. I suppose such is life?

I'm currently trying to see if just soaking rocks in water and changing water until copper levels read low will work. Have some rocks in a bucket with heater.

You could run a reactor with a copper absorbing media like cuprisorb.

Bleach will only degrade organics and not affect copper. I would be hesitant about trusting the Hanna checker with readings that low. For soluble copper carbon can remove that from the water column.
