Info: Seachem Flourish Tabs™ Dosing Instructions

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 three to four 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.

Flourish Tabs™ Dosing Tables

The following dosing tables provide the "beginner" dose for various water volumes. Please note that while the table provides the typical tank floor dimensions, this is not a guarantee of the dimensions of every aquarium of that volume.  Measure your tank dimensions to know how Flourish Tabs™ should be best distributed.
