    I have been an aquarist since 1964 and a reef hobbyist since the mid-1980’s. I am the owner of a small laboratory (Riddle Aquatic Laboratories) that specializes in investigation of interactions between light and water motion & photosynthetic organisms (especially corals). The results of this research, resulting in almost 250 articles, have been published in Advanced Aquarist Online, Aquarium Frontiers, Koralle, Freshwater and Marine Aquarium, The Breeders’ Registry, Aquarium Fish, Marine Fish Monthly and others. My first article was published in a 1984 SeaScope and relayed my experiences with a refugium – an idea that would catch fire about a decade later. I have had the honor of making over 60 presentations to various groups, including national conferences such as the Marine Aquarium Conference of North America (MACNA) International Marine Aquarium Conference (IMAC), PetsFestival (Italy), regional conferences, and local clubs. I received the Marine Aquarium Society of North America (MASNA) Aquarist of the Year Award in 2011 at the MACNA conference in Des Moines.

How to Grow Corals Quicker: Effects of Various Alkalinity Concentrations on Rates of Zooxanthellae Photosynthesis

Photosynthesis is the link between inorganic and organic worlds, and the importance of contributions made by zooxanthellae in maintaining health of photosynthetic corals is well known. We also know that rates of photosynthesis are dependent upon the amount of light, its spectral quality, as well as a supply of nutrients (for terrestrial plants, ‘nutrient’ is generally defined as nitrogen, potassium and phosphorus with ‘micronutrients’ described as iron, copper, and a host of others.)…
