Hello,
I posted the thread below in the reef chemistry forum. I've taken all of Jonathan's advice so far (new carbon, polyfilter, will do 10% water change tonight). I also tested iodate this morning and it was colorless, so below 0.03. The polyfilter hasn't changed color indicating copper or anything else toxic. Corals still look the same as the pictures in the thread.
Any other ideas? Thanks for the help.
