sera is a company that was founded in 1970 by Josef Ravnak, a seller of live pet food. Headquarters of the company are in Heinsberg (North-Rhine Westfalia), Germany. At this time, a new process called lyophilization was being introduced and was already highly acclaimed for preserving food animals with optimal retention of their nutrients and vitamins. Ravnak capitalized on this innovation, and over the years has continually improved sera's product quality. The name sera is a combination of Ravnak's first name, SEpp (nickname of Josef), and his family name, RAvnak. ==The early years== During the company's first years the product line was continuously expanded and optimized, and ''sera vipan'' flakes, the company's flagship food, was introduced in 1972. The company focus broadened to include the aquarium hobby as a whole and throughout the decade they developed water conditioners, such as ''sera aqutan'' and ''sera morena'' – aquatic plant fertilizers, such as ''sera florena'' – and aquarium fish medications, such as ''sera costapur'' and ''sera baktopur''. The first series of water testing kits were also developed. Towards the end of the seventies, sera turned to the garden pond sector and developed a complete range of pond care products. Turtle and other reptile products were also being added at this time. Throughout the eighties, sera continued to raise the company profile by increasing the product lines with innovative and scientifically advanced foods, vitamins, and technological products. During these years the acclaimed sera ''Bio-Denitrator'' was launched, which was the first mechanism to actively target the biological breakdown of nitrate in an aquarium. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Sera (company)」の詳細全文を読む スポンサード リンク
