Copper issue help

tmccaff · May 5, 2025

My latest icp test still shows my copper high. I am using cuprisorb and poly filter I did take them out as it wasn’t changing color but now thinking putting back in.

Will the Ati copper test show copper?

The test shows 28.65 u/l on icp

Can you post the whole icp result?

Brass is made of copper and zinc, both of which are very high. I’d review your whole system, including any post di parts of an ro/di for brass.

I had a pump break in system and smoke thinking this was the cause. I took all the water out scrubbed rocks and replaced sand. I’m going to add metasorb and poly fiber that will help right?

Would the Ati copper test detect copper at this level? I want to see what I can check to see if it’s working or icp only way

Yes, that sounds like a good plan. Poly fiber means a polyfilter, right?

There’s no useful at home tests for this purpose.

Ok, my Triton test came back and copper is now 7 u/l. Zinc 20 u/l I did this test a week after Ati one. Copper is coming down and now running Mtasorb with polyfilter my polyfilter never turned blue it’s a slight brown color. Is it possible now copper is gone? I have been running metasorb for 2 days now my plan is to run till Monday and take another ATI test. My polyfilter never turned blue though.
