In this episode of the INFLOW podcast, hosts Joe Arlotto and Dr. Jeff Keaffaber sit down with Zack Behrendt of American Sealants, Inc. for an in-depth conversation about the critical role acrylic plays in modern aquarium design, aquatic animal life support systems, and large-scale habitat construction.
From massive viewing panels and underwater tunnels to structural bonding, waterproofing, and long-term maintenance, Zack shares expert insight into the engineering challenges behind public aquariums, zoos, marine mammal habitats, and aquatic exhibits. The discussion explores how acrylic technology has evolved, why proper sealing and installation are essential for animal safety and water quality, and how operators and designers can avoid costly failures in aquarium infrastructure.
Whether you work in aquarium life support systems (LSS), aquatic engineering, exhibit fabrication, public aquarium operations, or marine construction, this episode delivers valuable knowledge on acrylic systems, aquarium maintenance, exhibit longevity, and the intersection of engineering and animal care.
