This is most likely residual media being discharged from your Berkey® Fluoride and Arsenic Reduction Elements. The media within them is inert and non-water soluble, so it is not a health concern. To resolve the issue, we recommend re-priming your elements from both sides for 20-30 seconds (each side). This should dislodge any remaining loose media within the element and leave clear water in your bottom chamber.
