Help needed, high copper level!

[bucfan]

Just got my ICP results and all parameters were spot on except for copper which was at 4.75 ppb. Not sure where copper is getting into my tank from and what must I use to lower it. Any suggestions please?

Cuprisorb to remove copper and heavy metals.
What kind of filter system for your water is being used? Where are you getting your water?

Have a 4-stage RO system to prepare my own water. Been using it for years.

Hmmm....the system should remove the copper if all filters are good.
Whats the history of all the rock in the tank?

Looking for help. Trying to isolate the problem. RO water had 0 copper or heavy metals. Looking at tank to see where the copper is coming from. Been running Rowaphos in tank. Do not supplement anything other than A/B. Where could the copper/heavy metals be coming from - heater, magnets, pump impeller? No metal plumbing parts. Doubt Rowaphos cause that is iron. Also at 4.75 ppb could copper affect corals? Plan to try Cuprisorb and Metasorb for 2 weeks. But then if I cannot figure the source then it will come back!
