Anyone notice copper in their NSW mix. Bought a hanna copper HR for my QT tank so I decided to check my NSW for curiosity. I’m reading .07-.09 ppm copper on three different buckets of Tropic Marin pro reef salt. Tested my brute trash can that has 4 year old live rock cooking from my old 220 reef tank and that’s reading .25ppm copper? Here’s a pic of my old reef tank, could never keep Euphyllia alive, wonder if this was the cause.
