Flourish tabs are a fertilizer for your plants in a solid form.  They will stimulate your plant's growth becasue they contain all essential trace elements, amino acids, and vitamins. They are also rich in iron, manganese, magnesium, calcium, potassium, inositol, chlorine b12, biotin, and other factors that have been determined to be beneficial to aquatic plant roots. Importantly, the tabs don't have any phosphate or nitrate so you can rest assured that they will not promote algae in your tank. Each pack of 10 tablets treats a 12" x 30" inch plant bed two times. Also available in a pack of 40. For best results, use in these tabs together with other liquid fertilizers.


Insert one Seachem Flourish Tab in the substrate every 4-6 in. apart. A standard 10 gallon aquarium requires only 6 tabs and the tablets should be distributed evenly throughout the gravel bed. Push each tablet midway into the gravel bed. New tablets can be added once every three to four months for optimal plant growth. The tabs will not alter pH levels, but, in very soft or unbuffered water, they have slightly acidic properties similar to peat moss.

    better than capsules

    Posted by john russo on 6 Aug 2021

    I bought root fertilizer from another vendor. They were capsules, which float if you don't get them deep enough in the gravel. My tank is 180 gallons, so I have to use long twezers. Flourish is tablets. They sink and are much easier to place.
