AQUARIUM FRONTIERS - United States of America
Karl Coyne is known for his iconic and impressive custom aquariums. Here Karl was featured in the Scientific Aquatic Journal for Advanced Reef Keeping, Aquarium Frontiers. Karl cites all the criteria within this live reef aquarium and classifies all the parameters including the scientific names of the inhabitants. Karl was one of the first researchers to successfully reproduce over two dozen coral species. Filtration, lighting, nutrition, and other parameters are also detailed.

Two identical half-cylinder aquariums were designed, one saltwater aquarium on the first floor of this business center, and another freshwater aquarium on the fifth floor. Both aquariums were much bigger than they appear (33,000 liters//9000 gallons). For quite some time, these were the biggest aquariums in Eastern Europe.

Excerpt from article: To maintain aquarium water that is low in nutrient compounds, Dr. Walter Adey of the Smithsonian Institution places heavy emphasis on the role of specially cultivated "turfs" composed of various species of algae (Adey and Loveland, 1991). This is commonly known as the Algal Turf-Scrubber approach, and it is currently more common in institutional aquarium installations than in the hobbyist world. Periodic harvesting of a portion of the algae growth serves to export accumulated wastes. Such systems rely heavily upon small organisms present in the live sand help to keep the substrate healthy, while denitrifying bacteria thrive in the low-to-zero oxygen conditions at the bottom. 

This approach has been closely investigated by Dr. Jean Jaubert at the national aquarium of Monaco, world-renowned for its displays of captive corals and its coral biology research. Its immediate appeal is the prevention of an accumulation of nitrate in the system by enhancing natural denitrification. A stunning live rock and live sand reef system created by Karl Coyne exhibits a dense stocking of many types of soft and stony corals.
