My RO/DI is functioning quite well. My clams have shown some signs of bleaching throughout my reef keeping experience from-time-to-time, even before I had put the wrasses in.
I however have never tested for heavy metals. I have all the materials inbound and will be sending a water sample out to a lab as well.
