Nalidixic acid is an antibiotic, belonging to the quinolone group, with a
wide spectrum of activity, and registered for use with food fish in some
European countries and Japan, although not the US. Also used for other
veterinary purposes, and in human medicine. It is of no use as a
flocculent, as far as I know. Perhaps you mean silicic acid?
