Planted Aquarium Concepts Aquarium Root Fertiliser Tabs, 40 Count, Slow-Release Nutrition

Planted Aquarium Concepts Aquarium Plant Root Fertilizer Tabs are 40-count, slow-release tablets made to supply rooted aquatic plants with nutrients through the substrate, with each tablet about 1 cm cube.

• 40 root fertilizer tabs — provides a supply of tablets for planted aquarium substrate.
• Slow-release fertilizer blend — delivers nutrients in the substrate where rooted plants can access them.
• Root-level placement — position tabs near plant bases or space them through the substrate.
• Replace after 3 months — sets a clear interval for renewing the tabs.
• For gravel beds or aquatic substrate — made for tanks with at least 1–2 inches (2.5–5.1 cm) of substrate.

Rooted aquarium plants take up nutrients through the substrate around their roots. These tabs are made for planted tanks where that root-zone supply is needed, including gravel beds and other aquatic substrates. Pressing the tablets into the bed puts the slow-release fertilizer near the plants, rather than leaving the tablets on the surface.

How should I place the fertilizer tabs?

Press each tab deeply into the substrate near the base of a rooted plant, or position tabs 3–6 inches (7.6–15.2 cm) apart. The tabs release a balanced blend of fertilizer to supply aquatic plants with nutrients where and when they need them. Adjust spacing to suit the planting density: closely planted areas may need different spacing from more open areas.

• Use in tanks with at least 1–2 inches (2.5–5.1 cm) of substrate.
• Press the tabs below the substrate surface.
• Replace tabs after 3 months.

What nutrients are in each tab?

The guaranteed analysis includes primary nutrients, secondary nutrients and trace elements. The listed percentages are nitrogen (N) 1.33%, phosphate (P2O5) 0.65%, potash (K2O) 5.18%, calcium (Ca) 0.22%, magnesium (Mg) 0.215% and sulfur (S) 1.12%.

• Iron (Fe): 2.3%; manganese (Mn): 0.1935%.
• Boron (B): 0.02%; zinc (Zn): 0.0091%.
• Molybdenum (Mo): 0.0021%; cobalt (Co): 0.0015%; nickel (Ni): 0.0002%.

What are the tablet size and storage instructions?

Each tablet is about a 1 cm cube and weighs about 0.68 +/- 0.1 grams. Keep the bag sealed and store it at room temperature. These product details help planted-aquarium keepers plan how the tabs fit into their substrate routine and how to store the remaining supply between uses.

• Tablet size: approximately 1 cm cube.
• Tablet weight: approximately 0.68 +/- 0.1 grams.
• Storage: room temperature with the bag sealed.

These root fertilizer tabs suit aquarium keepers growing rooted live plants in a gravel bed or aquatic substrate with sufficient depth for tabs to be pressed in. They are intended for substrate-based nutrient delivery to rooted plants, rather than placement loose on the surface. Their slow-release blend, root-zone placement and three-month replacement interval define a straightforward feeding routine for planted tanks.
