Osmocote Root Tabs – Long-Lasting Nutrient Support for Planted Aquariums

Boost Rooted Plant Growth with Time-Release Fertilizer Pellets

Osmocote Root Tabs provide an effective and economical way to deliver essential nutrients directly to the root zones of aquatic plants. Made with slow-release Osmocote fertilizer, these tabs are ideal for heavily planted tanks and rooted species such as Amazon swords, cryptocorynes, vallisneria, and carpeting plants.

Each root tab is packed with a balanced blend of macronutrients (NPK) and essential micronutrients that are gradually released over time, helping promote lush foliage, strong root systems, and vibrant plant coloration. Because the nutrients are released slowly beneath the substrate, they minimize water column contamination and help prevent algae blooms—making Osmocote tabs a favorite among aquascaping enthusiasts and planted tank keepers.

Key Benefits:

• Direct-to-Root Feeding: Places nutrients right where rooted plants need them most

• Slow-Release Formula: Provides consistent fertilization for up to 1–3 months per tab

• Supports Healthy Growth: Boosts root development, leaf density, and color vibrancy

• Low Risk of Algae: Nutrients remain concentrated in the substrate rather than the water column

• Cost-Effective: Affordable, high-performance alternative to commercial aquarium-specific root tabs

Ideal For:

• Planted freshwater aquariums

• Aquascapes with nutrient-demanding rooted species

• Tanks using inert substrates like sand or gravel

• Hobbyists looking to supplement liquid fertilizers or CO₂ injection

How to Use:

1. Insert tabs deep into the substrate near plant bases (using tweezers if needed).

2. Space tabs approximately 4–6 inches apart, depending on plant density.

3. Replace every 1–3 months or when plant growth slows.

4. Monitor plant health and algae levels to adjust frequency if needed.

Available in multiple quantity packs to suit tanks of all sizes. While not marketed specifically for aquarium use, Osmocote root tabs are widely used by aquarists seeking an efficient and affordable fertilization method for their planted tanks.

Give your rooted plants the nutrient boost they deserve with Osmocote Root Tabs—trusted by hobbyists for reliable, long-term plant care.
