I think maybe your waterchanges aren't very effective. Could you describe how you do a waterchange? What steps do you follow? Do you use RO/DI water or tap water? If RO/DI, have you checked the TDS of the product water?
Even though Metro is generally considered reef-safe(ish?), it's not something I would be adding to my reef.
