Are any of the chemicals available overseas safer for reefs and sealife?

@e_kelley The research on UV filters and coral isn’t as cut and dry as some media coverage would lead you to believe. But the safest bet for coral and other sea life is your mineral UV filters, TiO2 and ZnO. It’s also likely that the newer organic filters like BEMT will be better for sea life for the same reason they’re safer for humans; the high molecular weight sharply lowers bioavailability.
