So the LFS I go to has yellow water in their fish only tanks. Is this because they are dosing with something like ruby reef rally? They said they're running copper but I tested the store water and it was only at 0.08ppm. I'm also testing with a Hannah checker which I think is only compatible with certain types of copper. Could the test have been skewed due to the yellow tint? There was little to no color change when adding the reagent. Or maybe it read 0.08ppm because of the yellow hue?
Thanks!
