  • Ep 18 - Evolution of Aquarium LSS: Chemistry, Microbiology & Ozone Mastery with David LaBonne
    2025/07/09

    Joe Arlotto and Dr. Jeff Keaffaber dive deep into the world of aquatic life support systems (LSS) with special guest David LaBonne, a pioneering microbiologist and former Director of Facilities at the National Aquarium in Baltimore.

    David shares his remarkable journey from microbiology and immunodiagnostics to redefining how public aquariums approach water chemistry, ozone disinfection, and microbiome management. From early challenges with coliform counts and ozone tower inefficiencies to introducing data-driven filtration protocols and backwash recovery, David has shaped the modern aquatic systems landscape.

  • Ep 17 - Facility Spotlight: The Maritime Aquarium
    2025/07/02

    We're excited introduce our new Facility Spotlight series! Hosts Joe Arlotto and Dr. Jeff Keaffaber go in-depth on the Maritime Aquarium in Norwalk, Connecticut, with a behind-the-scenes conversation featuring Erik Holmberg, Associate Director of Life Support.

    Erik shares his hands-on journey from general maintenance to LSS leadership, detailing his role in system upgrades, daily operations, emergency responses, and long-term infrastructure improvements. From retrofitting 30-year-old systems to pioneering backwash recovery and ozone contact upgrades, Erik walks us through what it really takes to keep complex aquatic habitats running smoothly with a small but mighty team.

    We've got helpful insights for operators, facility managers, and designers—from choosing media and managing turnover rates to advocating for capital projects. If you're passionate about aquatic animal health, system reliability, or making the most of limited resources, this is a must-listen.
