About Us


AALSO members are the water quality and mechanical system professionals that move the water, design and maintain the systems, develop and distribute the products to manage the daily requirements for animals in our care at hundreds of facilities across the world. We care for the systems that make animal care possible. We are a 501 c6 nonprofit organization focusing on the education and training of aquatic life support operators around the world. We as an organization do not act as a consultant to our members directly regarding projects or problems, however we create a pathway for our members to learn about the latest technology in the industry and act as a forum for members to connect and discuss the care of aquatic animals in captivity. Formed in 1994 we are supported by the entire industry. From operators to vendors and researchers to administrators, we are the premier professional organization dedicated to this multifaceted discipline. If you have ever selected or maintained a pump, glued PVC pipe, adjusted an ozonator, measured dissolved oxygen, pH or ammonia, measured flow or temperature, open or closed a valve, chances are you are less than two removes from an AALSO member!
