Problem | hydrogen sulfide | high nitrate | Pathogen potential, Vibrio sp. bacteria, Yersinia ruckeri | small hydrocarbon slicks | Essential antibiotic or sterilization | anaerobic conditions | foul odors |
Effect | reducing the formation of hydrogen sulfide | removing nitrate from the system as nitrogen gas | General probiotic effect on live animals, competes with pathogenic bacteria, decreased (luminous) vibrio | Botryococcus braunii algae or by a petroleum spill reduction | repopulates the system after antibiotic use | Reduces anaerobic conditions | Reduces foul odours |
