September 14 2018 – Meeting

Friday, September 14th at 8 pm

Adam Leff, DVM, MS, Associate Professor of Biological Sciences at Kent State University will present his recent research on aquarium additive products that claim to aid in the nitrogen cycling of a tank. In his presentation, titled “Bacteria and the Nitrogen Cycle in Aquarium Systems: A Look at the Efficacy of Aquarium Supplements,” Dr. Leff will focus on the microbiology of biofiltration, with emphasis on the bacteria involved in nitrogen cycling. The talk will attempt to answer the following questions:

  • What bacteria are involved in the nitrogen cycle of an aquarium system?
  • What are the characteristics of these bacteria?
  • What happens to these bacteria when the system is perturbed (in other words, when things go bad, why do they go bad quickly?)
  • How can you optimize your aquarium system to achieve maximal “biofiltration”
  • Do aquarium additive products that claim to increase the biological filtration and aid in the nitrogen cycling of a tank really work?

Bio for Dr. Leff  

Adam Leff, DVM, MS

Dr. Leff received his Doctorate in Veterinary Medicine and his Masters of Science degree in Medical Microbiology from the University of Georgia in Athens, Georgia. His research focus at Georgia involved the immune response of Channel Catfish to the protozoan parasite, Ichthyophthirius multifiliis. He has been an Associate Professor of Biological Sciences for the past 23 years at Kent State University. While at Kent, his research focus has been in the field of aquatic microbiology including research studies on the microbiological cause of black shell disease in crayfish, the interaction of environmental bacteria with aquatic macroinvertebrates, and the bacterial composition of leachate from shredded tire landfills. Dr. Leff teaches a variety of courses at Kent State including Microbiology, Ichthyology, Anatomy and Physiology, and Medical Histology. He has been an aquarium hobbyist since he was eight years old.
