Masterline Root Caps slow-release aquarium fertilizer for healthy roots

Masterline Root Caps slow-release fertilizer for planted aquariums

Masterline Root Caps are a premium slow-release nutrient solution designed to deliver essential macro and micro nutrients directly to the roots of aquatic plants. Each capsule ensures plants receive the optimal balance of nitrogen, phosphorus, potassium, magnesium, iron, and trace elements for strong root growth, healthy leaves, and vibrant colors.

These root capsules are especially beneficial for delicate and slow-growing plants that require steady nutrition over time. Gradually releasing nutrients, they transform inert substrates into rich, fertile soil, revitalizing aquariums where nutrients are depleted. The result is a thriving planted aquarium with improved plant stability and lush growth.

Masterline Root Caps are entirely safe for shrimp, fish, and all aquatic life. The capsules do not alter water quality and can be easily removed after the nutrients are fully absorbed, ensuring a clean and balanced aquarium ecosystem.

Dosage and usage instructions

• Insert capsules deep into the substrate, under plant roots, using tweezers for precise placement
• Space capsules are approximately 10 cm apart to ensure uniform nutrient distribution
• Refresh capsules approximately every three months or as necessary to maintain nutrient levels
• Reinsert capsules that surface back into the substrate, and vacuum consumed capsules to maintain substrate cleanliness
• Combine with Masterline liquid fertilizers for enhanced nutrient availability and plant growth

Recommendations and precautions

• Monitor plant growth regularly and supplement with liquid fertilizers as needed
• Handle capsules carefully and avoid contact with skin or eyes; rinse immediately if contact occurs
• Keep out of reach of children and pets
• Store in a cool, dry location away from sunlight, frost, and extreme heat
