Cuprisorb will work to remove copper, but a poly filter would be a better option. So long as the poly filter remains blue you know copper is still present in the water; once it turns white you should be good to go. Of course, you will need to run the poly filter for months to ensure all the copper absorbed by the rocks/sand has all leached back out into the water. :(

I have already remove all live rocks and sand to play safe. Changed the water and have to wait and see now. [emoji27]
