The most comprehensive all-you-will-ever-need-to-know guide for maintaining captive reef fish, corals, and invertebrates from a qualified scientific author with over forty-five years of domestic and commercial practical experience. This is a single resource promoting the reader from zero understanding to advanced aquarist. Whether managing home reef or fish-only systems, commercial export/retail systems, large public displays or doing objective science, this volume features all aspects of marine husbandry including system design/maintenance, trace element and DIY supplement formulations, reef/fish lighting and DIY LED pendants, reef pest/parasite control, nutrient and algae management, fish/coral nutrition and compatibility, aquascaping and decor, reef conservation, captive/wild coral culture, coral/fish disease microscopy-based diagnostics and mitigation using host defences and safe DIY chemotherapeutics. Until we fully appreciate what is happening at the atomic level and beyond, we cannot truly comprehend how husbandry practices impact system dynamics and the animals we wish to nurture. This book explores the hitherto "assumed" fundamentals of inorganic/organic chemistry, microbiology, biochemistry, molecular biology, genetics, and virology. Combines cutting-edge scientific and practical know-how explained in simple terms.
