The best AQUARIUM CO2 SYSTEMS in 2024 - Detailed Product Descriptions
1. Seachem Flourish Tabs Growth Supplement - Aquatic Plant Stimulant 10 ct
More PhotoGROWTH TREATMENT: Seachem Flourish Tabs are growth stimulating tablets for plant roots which contain essential trace elements, amino acids, and vitamins.
VITAMINS: Seachem Flourish Tabs 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.
NUTRIENTS: When inserted into the gravel, Seachem Flourish Tabs provide direct, time-released fertilization to the plants’ root zone. Nutrients are slowly made available through enzymatic action of the plants’ roots on the tabs.
TANK USE: 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, pushing each tablet midway into the gravel bed.
COMPLETE MAINTENANCE: For optimal plant growth, add new Flourish Tabs to the aquarium once every three to four. Seachem Flourish Tabs will not alter pH, however, in very soft or unbuffered water, they have slightly acidic properties similar to peat moss.
