## Description

Seachem 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 the lack of available solutions to aquarists'.. 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. While Seachem has grown rapidly into a national and international firm, it retains the culture of a small company and is readily available to its customers.

Review: If you have plants in your tanks, you need this - This is the ideal plant fertilizer for tropical aquariums, at least in the US. It is the only liquid fertilizer that I have seen that is comprehensive, which means it has all the nutrients needed for plant growth and in the right proportions. Most fertilizers I have seen only contain a couple, for example Iron and Potassium (Potash). Flourish has in it: Total Nitrogen 0.07% Available Phosphate ( P2O5) 0.01% Soluble Potash 0.37% Calcium (Ca) 0.14% Magnesium (Mg) 0.11% Sulfur (S) 0.2773% Boron (B) 0.009% Chlorine (Cl) 1.15% Cobalt (Co) 0.0004% Copper (Cu) 0.0001% Iron (Fe) 0.32% Manganese (Mn) 0.0118% Molybdenum (Mo) 0.0009% Sodium (Na) 0.13% Zinc (Zn) 0.0007% The dose for this is pretty minimal, so if all you have is a single tank of small to moderate size you should just get the 250 mL or 500 mL bottle. As an example, a 20g tank only needs a dose of 1.6 mL per week so a 250 mL bottle would last you 156 weeks which is a little short of 3 years! The good news is, this product does not expire so having it around for that long is not an issue. If you have a large tank, you can get Flourish in a larger bottle. I have a 125g, 20g, 10g, and 5g aquarium to dose weekly so I use the 2 L bottle. Plus, if you look at price, a 2 L bottle is far cheaper than buying four 500 mL bottles. So buy in bulk if you need it, it won't go bad! I do keep mine in the refrigerator though. The label says you don't need to, but I figure there must be some reason they recommend it. Tip: Add your Flourish 24 hours after your weekly water change. The reason being most water conditioners will bind to 'heavy metals' of which flourish does contain some (for example copper). Plants need this, so you want to keep it available to them. Don't worry about your fish, the levels are extremely low. Second Tip: If you have moderate to bright lighting, you may wish to try doing two doses a week. Light and nutrients must remain in balance, or you'll have algae issues.
Review: Love this product for my planted tank - Awseome product and great value
