Seachem Flourish Freshwater Plant Supplement 500 mlSeachem Flourish is a comprehensive plant supplement for the natural freshwater aquarium, containing a rich assortment of important micro elements, trace elements and other nutrients.For over three decades, Seachem has been a company rooted in sound science. Our experience in the hobby and an educated staff of chemists and biologists are part of the package when you purchase Seachem products. Seachem remains as one of the few surviving independent and privately owned pet care companies. Seachem is owned and operated by hobbyists . All of our employees are hobbyists who maintain aquariums at home and at the office. Seachem itself was started because one such passionate hobbyist - Dr. Leo G. Morin (Founder) - recognized that the available solutions to aquarists problem wanting. This resulted in Seachem’s very first product: Cupraplex (today known as Cupramine). Over thirty years later Seachem is still approaching old problems in a new way. Seachem’s philosophy is that the knowledgeable hobbyist makes the best customer. This is reflected in solid and reliable customer education and support as well as products proven in science and performance.

Use Flourish Potassium to prevent potassium depletion and maintain the highest level of growth. Flourish Potassium is an integral component of Sachem's plant products and is recommended for use with the entire Flourish line as well as our Fluorite gravel. Contains no phosphate or nitrate.
