Back Cover info - "Throughout this major new publication, the authors - all experts in their own fields - have delved deeper than in any other equivalent book. The result is that the facts are not only clearly explained but are backed up with the relevant scientific reasoning so the reader can truly understand the whole picture. This applies as much to the biological and chemical processes involved in maintaining water quality as it does to the protein content of the best foods to keep Koi healthy and growing. This valuable resource of information is illustrated with the finest colour photographs and computer graphics that reveal the working principles of filters and other equipment in stunning quality. The hobby has changed markedly over the past tweny years and this book reflects current thinking and the latest technical advances"
