Seachem Flourish Tabs – Aquarium Root Tablets for Planted Tanks | India
Seachem Flourish Tabs are nutrient-rich root tablets you insert into the gravel or substrate to feed root-hungry aquarium plants directly at their roots. Plants like Amazon swords, cryptocoryne and vallisneria draw most of their nutrition through their roots, and Flourish Tabs deliver a slow-release supply of iron, trace elements and other nutrients right where they need it. The perfect substrate partner to a liquid fertilizer — premium Seachem quality for planted tanks in India.
What are Seachem Flourish Tabs?
Short answer: Slow-release fertilizer tablets for the substrate, feeding root-feeding aquarium plants directly.
While liquid fertilizers feed the water column, root tabs feed the substrate — the zone where heavy root-feeders take up nutrients. You push a tab into the gravel near a plant’s roots, and it releases nutrients slowly over months. Flourish Tabs are rich in iron and trace elements to support strong root growth. For a value India-made alternative, see Sunken Garden Root Tabs. Learn when to use them in our root tabs vs liquid fertilizer guide.
Key Features
- Substrate root feeding — nutrients delivered straight to the roots.
- Slow release — one placement lasts for months.
- Iron & trace rich — supports strong root growth and colour.
- Premium Seachem quality — a trusted planted-tank brand.
- Great for heavy root-feeders — swords, crypts, vallisneria.
Benefits
Immediate: Heavy root-feeders get a concentrated nutrient supply at the roots.
Short-term: Stronger roots and healthier growth in swords, crypts and vallis.
Long-term: Sustained substrate fertility for months from a single placement.
How They Work
Buried in the substrate, each tab slowly releases nutrients into the root zone, where root-feeding plants absorb them directly. This complements water-column dosing: your liquid fertilizer feeds stem plants and mosses, while root tabs feed the heavy root-feeders. Together they cover every plant in a mixed aquascape. See the nutrient groups in our macro vs micro guide.

How to Use
- Push a tab into the substrate, near the roots of a root-feeding plant.

Frequently Asked Questions
What are Seachem Flourish Tabs?
Nutrient tablets inserted into the substrate to feed root-feeding plants directly at their roots, releasing slowly over months.
Which plants need root tabs?
Heavy root-feeders such as Amazon swords, cryptocoryne, vallisneria and bulb plants.
How often do I replace them?
Per the Seachem label, typically every few months or when root-feeders slow down.
How deep do I push them?
Into the substrate near the roots, fully buried so nutrients release below, not into the water.
Are they safe for fish and shrimp?
Yes — buried in the substrate they release slowly and safely. Avoid disturbing buried tabs.
Do I still need liquid fertilizer?
Yes — root tabs feed root-feeders; water-column plants still need a liquid fertilizer.
What if a tab surfaces?
Re-bury it. Exposed tabs release nutrients into the water column, which can feed algae.
Do they work in gravel and sand?
Yes — they add fertility to inert substrates like gravel and sand. Bury fully.
How are they different from Sunken Garden Root Tabs?
Both feed root plants in the substrate; Sunken Garden Root Tabs are a value India-made option, while Flourish Tabs are the premium Seachem choice.
Can root tabs be my only fertilizer?
Only if you grow exclusively root-feeders. Most mixed tanks need liquid as well.
