Seachem Flouris Trace elements(tranquilizer)?

Just wondering if this happens to anyone else too .When i add 4 1/2 caps seachem flourish trace elements once or twice a week, and then after a hour i put it in the tank ,i notice my fish just hanging around dazed (not active like they're always are )and than a half hour later passes , they're scavenging the bottom of the tank looking for food (wth). Than after they are done scavenging the sand bed for about half hour ,they go back to their normal selves chasing each other


wth is in this seachem flourish ? thc ?
