Feed Hungry Roots Right Where They Grow Root-feeding plants pull most of their nutrition from the substrate, so even a well-dosed water column leaves them starved. Liquid ferts alone can't reach the root zone where these plants need it most. Seachem Flourish Tabs are growth-stimulating tablets packed with essential trace elements, amino acids, and vitamins, rich in iron, manganese, magnesium, calcium, potassium, inositol, choline B12, biotin, and more. Pushed into the gravel, they deliver direct, time-released fertilization to the root zone through enzymatic action, and they contain no phosphate or nitrate that would fuel algae. Perfect for beginners, they put all the nutrients of Flourish into a convenient dry, tablet form. Flourish Tabs come from Seachem Laboratories, the science-driven aquatics company founded in 1979 in Madison, Georgia, where in-house chemists formulate every product. They are the substrate-feeding member of the coordinated Flourish planted-tank system, putting Flourish's nutrient profile directly into the root zone to complement Flourish Excel's carbon and the water-column dosing of nitrogen, phosphorus, potassium, iron, and trace elements. Insert one tab in the gravel for every 10–15 cm (4–6 in.) radius, pushing each midway into the bed. Distribute evenly (a standard 10 gallon aquarium requires 6 tabs). Replace once every three to four months for optimal growth. Give your rooted plants the buried nutrition they crave. Add to cart. What It DoesGrowth-stimulating root tablets rich in iron, manganese, magnesium, calcium, potassium, inositol, choline B12, biotin, and other factors beneficial to aquatic plant roots. Contain no phosphate or nitrate that would promote algae. Provide direct, time-released fertilization to the root zone via enzymatic action. Each pack of ten tablets treats a 12 x 30 inch plant bed twice. Tabs will not alter pH, but in very soft or unbuffered water they have slightly acidic properties similar to peat moss. DirectionsInsert 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 three to four months for optimal plant growth.

Available Sizes10 count, 40 count Why Seachem Flourish Tabs Root-zone member of the Flourish system: delivers nutrition straight into the substrate where liquid dosing can't reach, complementing water-column ferts and Flourish Excel's carbon. Bioavailable, time-released nutrients: feed the root zone gradually through enzymatic action, drawing on ferrous gluconate iron and a broad trace profile. Fixes root-feeder starvation: supplies buried nutrition for substrate-rooted plants that stay hungry even in a well-dosed water column, without adding phosphate or nitrate to fuel algae. Iron-rich analysis: guaranteed Iron (Fe) 2.2% plus manganese, calcium, and other elements, dosed at one tab per 10–15 cm (4–6 in.) radius. Best For Ideal for low-tech and high-tech planted tanks with substrate-rooted, heavy-feeding plants such as swords, crypts, and other rosette species that draw nutrition from the gravel. Best for aquarists whose root-feeders lag despite good water-column dosing, and a convenient dry starting point for beginners. FAQ How many tabs do I use and how often? Insert one tab for every 10–15 cm (4–6 in.) radius (a standard 10 gallon tank needs 6), distributed evenly and pushed midway into the gravel, then replace once every three to four months. Will Flourish Tabs cause algae? They contain no phosphate or nitrate that would promote algae, so they feed roots without fueling nuisance growth. How does this fit with the rest of the Flourish line? Flourish Tabs handle substrate feeding in Seachem's coordinated planted-tank system, working alongside the comprehensive Flourish supplement, Flourish Excel for carbon, and targeted NPK, iron, and trace dosing in the water column.
