Here are two brand new photo-filled volumes in a fine and growing series for aquarium hobbyists. Tankmaster volumes show -- rather than merely tell -- exactly how to set up and maintain different kinds of aquarium. Every page is filled with step-by-step, instructive full-color photographs and diagrams that guide aquarium hobbyists through a wide variety of projects. Detailed picture captions and labels complement the step-by-step illustrations and fully explain them. More than 200 vivid full-color photos in every volume.An aquarium for goldfish, ornamental carp, and other coldwater varieties doesn't require as much technology as the tropical aquarium, but the fish hobbyist still must be aware of important "do's" and "don'ts". This book advises on gravel, appropriate rocks and plants, filtration, lighting, and water-changing schedules.
