Meet the specialist - John Catanzaro - I have been working with aquariums for over 15 years. I have extensive knowledge on aquarium maintenance, coral reef construction, and care for all organisms. I have trained with marine biologists and chemists and have a refined understanding of all phases of marine organism care and water quality. I have maintained tanks ranging from tens of gallons to thousands of gallons. I have been a member of the Brooklyn Aquarium Society for many years and look forward to the opportunity to serve you.
