Flourish Tabs™ are growth stimulating tablets for plant roots. They contain essential trace elements, amino acids, and vitamins. They are rich in iron, manganese, magnesium, calcium, potassium, inositol, choline B12, biotin, and other factors that have been determined to be beneficial to aquatic plant roots. View a chart of Flourish Tabs™ constituents and signs of their deficiency. They contain no phosphate or nitrate that would promote algae proliferation. Each pack of ten tablets treats a 12 X 30 inch plant bed twice. 

Insert one Flourish Tab™ in the gravel for every 10–15 cm (4–6 in.) radius. A standard 10 gallon aquarium requires 6 tabs. Distribute the tablets evenly throughout the gravel bed. Push each tablet midway into the gravel bed. Add new tablets once every one to three months for optimal plant growth. Tabs will not alter pH, but, in very soft or unbuffered water, they have slightly acidic properties similar to peat moss.
