Heavy metal issue

[Greg B.]

A few months ago I set out on the journey to find out why every coral I've put into my tank died and everyone sive put in since have died. Just got back water testing a few weeks ago and I've broken my tank down to find the culprit of my heavy metal issue. Stupid me not thinking. A brass gate valve. Both have copper and zink in there. And the problem started shortly after adding it in. Stupid I know. Since breaking down I've done a huge water change(about 90%) and have been running cuprisorb in the tank for almost 2 weeks. Would you say that the majority of the heavy metal is out and I would be safe to try new coral? Or would you wait and do another ICP test? I'm gonna attach the icp test below.

90% with cooprizorb should be good.
I had a similar issue with tin.
I did a 50% water change with chemipure and two pouches of cooprizorb. Two days later another 60 and then 2 days later a 25.
Took the cooprizorb and chemipure out after a week. Corals all recovered.
Best to do another test but I’d say your probably good to go.

Just put a tester in there and see. Do you have anyone near you to get a frag from?

I do. Just wanted to get some opinions from others before I did it

If it was simple water it would be easier to predict removal than a reef tank where copper will bind to all kinds of surfaces to slow removal.

Two routes to go are:

1. A test coral or invert.
2 An icp test, preferably icp-ms
