I tested my water again, then made up some new water in a pitcher and tested to compare the two:

>both tests looked identical to the naked eye - perfectly clear

>however, my test kit only goes down to .05 mg/l, so could there still be toxic levels of copper that my test kit can't read?

>until last week, I had been running carbon in the filter, and put more back in today

>also, when I had that setup 2 years ago, and some time after I treated w/copper (free ionic), I purchased an LTA and cinnamon clown and both did very well. Will copper not affect anemones, just corals and such? If copper would affect LTA, and nothing (bad) happened to mine, can I assume my copper level acceptable?

(I just want to be 100% sure that copper levels are low enough before I put that filter and rock in my new tank)
