Marc was born in New York City in 1948 where there were always fish tanks in the house. His family moved near the sea when he was nine and marine life was soon added to his collection of freshwater fishes, turtles and plants. His aquaculture training was in Asia where he occasionally returns to lecture and consult. As an avid diver and explorer, he often traveled far from his present location in Ft. Lauderdale Florida. In fact, his first journey to the Amazon basin in 1974 opened his eyes to the biochemical interrelationships of the rain forest and reef environments. This led to the formation of Marc Weiss Companies Inc., which in turn led to the development and production of natural biological water conditioners, medications and additives for freshwater and marine aquariums, and the aquaculture and agriculture industry.
I've known Marc for well over ten years, both as a friend and a mentor. I'm happy to say that many advanced aquarists as well as myself think Marc's product line is among the most intelligent on the market. His natural approach to animal health and water quality is to be praised. I've not only used many of his products, as have many others, but understand their connection with the microbial processes in our aquariums.
Now that Marc has decided to get away from day-to-day business details and once again focus upon new product development, I wish him the best. Karen Weiss will continue, as she has in the past when Marc was travelling, to successfully operate the business.
