Not copper from the salt or pipes but from adding it to cure ich.
My rock has been in my system for over 30 years and I even had some metal poisonings from outside sources and the corals seem to be just fine.

hi Paul B
thanks for the reply - its funny bec your system was the first thing i was thinking about when i read this article from shimek... hasnt yours been set up over 30years? - how much of the original liverock/gravel/etc do you still have in the system?
dr shimek recoms using oolitic or fine sand for dsb
mentioning that its nec for all the fauna that lives w/n it to be able to survive VS thicker grain size...
when set up our system
we used 'reef floor' which is larger then the recom oolitic sand... i actually chose to go off calfos recom from one of his books which contradicts shimek somewhat... and i feel like we got lucky bec since this system has been established nitrates have never been an issue and i would suppose the dsb has a lot to do w/ this!...
but i do respect reading others opinions/experiences etc
espec those who are doing THE reasearch into so many of the hobby related issues we deal with... and i know i have learned a lot from reading shimeks articles/books
