Success in aquatic animal care isn't just about water chemistry—it's about the "bricks and mortar" that hold everything together. In this episode of Inflow, hosts Joe Arlotto and Dr. Jeff Keaffaber sit down with industry veteran Steve File, a long-standing leader and former board member of AALSO.

With decades of experience in facility operations and life support systems (LSS), Steve shares his perspective on why the LSS field is broadening to include everything from HVAC and electrical systems to complex concrete and rockwork fabrication. This conversation is a masterclass in bridging the gap between design, construction, and long-term operational success.

In this episode, we discuss:

• The Evolution of LSS: How the role of the life support operator has expanded from water quality to total facility infrastructure management.

• Strategic Facility Planning: Steve's insights on "building for longevity" and why getting the structural details right, like rebar placement and concrete cover, is critical for animal health.

• The "Operator as Educator": Why LSS professionals must take the lead on job sites to ensure contractors understand the unique requirements of aquatic habitats.

• Career Growth & Education: Steve's advice for the next generation of operators, including the value of cross-training in trades like HVAC and plumbing.

• The AALSO Community: A look ahead at the upcoming symposium in Kansas City and the importance of establishing face-to-face relationships with vendors and peers.

About Our Guest: Steve File is a highly respected figure in the aquatic animal industry, known for his leadership within the AALSO board and his deep expertise in the operational and structural side of zoo and aquarium facilities.
