Sunken Garden Root Tabs are nutrient-rich tablets you push into the aquarium substrate to feed root-hungry plants directly at their roots. Plants like Amazon swords, cryptocoryne and vallisneria draw most of their nutrition through their roots, and root tabs deliver a slow-release supply of nitrogen, phosphorus, potassium and trace elements right where they need it. Supplied as a value 6+1 pack and shrimp-safe, they are the perfect substrate partner to a liquid fertilizer — made in India for planted tanks.
What are Sunken Garden Root Tabs?
Short answer: Slow-release fertilizer tablets for the substrate, feeding root-feeding aquarium plants directly.
While liquid fertilizers feed the water column (and the plants that absorb through their leaves), root tabs feed the substrate — the zone where heavy root-feeders take up nutrients. You push a tab into the gravel or soil near a plant’s roots, and it releases nutrients slowly over months. Sunken Garden Root Tabs come in a handy 6+1 pack and are shrimp-safe. 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 around 3–4 months.
- Complete root nutrition — NPK plus trace elements.
- Value 6+1 pack — seven tabs for multiple plants.
- Shrimp & fish safe — safe when buried in the substrate.
- Made in India — affordable, reliably in stock.
Benefits
Immediate: Heavy root-feeders get a concentrated nutrient supply at the roots.
Short-term: Stronger root systems and healthier, faster 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 dissolves and 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 science in our macro vs micro nutrients guide.
Which Plants Need Root Tabs?
| Plant type | Needs root tabs? |
|---|---|
| Amazon swords | Yes — heavy root-feeder |
| Cryptocoryne (crypts) | Yes — root-feeder |
| Vallisneria | Yes — root-feeder |
| Bulb plants (aponogeton) | Yes — root-feeder |
| Stem plants, mosses, Anubias | No — feed via liquid |
How to Use
- Push a tab 2–3 cm into the substrate, near the roots of a root-feeding plant.
- Space tabs roughly every 8–10 cm across a planted area, or one per large root-feeder.
- Bury fully so nutrients release into the substrate, not the water.
- Replace every 3–4 months, or when growth slows.

If you grow Amazon swords, cryptocoryne or vallisneria, root tabs are essential. Use Sunken Garden Root Tabs in the substrate and a complete liquid like Sunken Garden Green in the water for complete coverage of every plant. Full comparison in root tabs vs liquid fertilizer.
Frequently Asked Questions
What are aquarium root tabs?
Nutrient tablets pushed 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 Sunken Garden Root Tabs?
Every 3–4 months, or sooner if root-feeders start growing slowly.
How many tabs do I need?
Roughly one per large root-feeder, or one every 8–10 cm across a planted area. The 6+1 pack covers several plants.
How deep do I push them?
About 2–3 cm into the substrate, near the roots, fully buried.
Are root tabs 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 (stems, mosses) 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.
Can root tabs be my only fertilizer?
Only if you grow exclusively root-feeders. Most mixed tanks need liquid as well.
Do they work in gravel and sand?
Yes — they add fertility to inert substrates like gravel and sand. Bury fully.
Will they cloud the water?
Not if buried properly. Cloudiness usually means a tab was crushed or left exposed.
Are they good value?
Yes — the 6+1 pack is an affordable, India-made way to feed root-feeding plants for months.
