Can't imagine it came from your RO source. Drinking water standards are <0.01 ppm, I believe. Maybe leaching off a piece of equipment? Or analysis mishap?Just had a high arsenic reading as well from ICP-Analysis. 0.055. Have been struggling with acropora for some time and wondering could this be the cause? I have no idea where this could be coming from.
