I am trying to determine if my Copper Levels are an issue. I have used Aquarium Water Testing to test my tank water. The Readings have been between .04 -.06 mg/L Copper. I have a decent RO/DI unit with new filters. I have used the product Cuprisorb and activated Carbon. In order to try and determine if the copper level was increasing from the time water comes out of the sink until it has been in my tank for a while - I took several water samples. One right from the faucet - one right out of the RO/DI unit - one after I prepared the salt and of course one from the tank.
Well it seems the levels really are about .04 mg/L throughout the whole process. The RO Unit is not reducing the tap water's copper content - the activated carbon and Cuprisorb are not reducing the levels and nothing in the tank seems t be adding to the copper level.
Should I be concerned about this level of copper? I have some corals - fish - fire shrimp and live rock. I was having some issues with my Hammer Coral and my Torch Coral and thought perhaps the copper levels had something to do with his. My other test results seemed ok.
Any thoughts or suggestions would be appreciated.

The most recent test results are below:
Copper (Cu)
Natural Seawater Value: 0.030 mg/L
Acceptable Range: 0 "“ 0.03 mg/L
Tested Result: 0.04 mg/L
(HIGH) Your copper level is too high. We recommend the use of activated carbon to reduce this level. You should also use only RO/DI water for make-up/top-off water, as most copper that gets into tanks comes from copper water pipes in the home. It is also an ingredient in many fish medications. Copper is an important trace mineral for metabolic processes in many marine organisms. However, levels above 0.05 are toxic to almost all invertebrates and some fish species
