Available sizes
Choose the size that best suits your aquarium setup, whether you are running a single tank or multiple high-demand systems.
Complete plant nutrition in one solution
Healthy aquatic plants require a combination of macro nutrients and trace elements to thrive. Masterline II combines everything into one easy-to-use formula, including:
- Nitrogen (N) for strong, leafy growth
- Phosphorus (P) for root and energy development
- Potassium (K) for overall plant health
- Iron (Fe) and trace elements for vibrant colour and balance
This balanced approach supports consistent growth, improved coloration, and stronger plant structure.
Ideal for high-demand planted aquariums
Masterline II is best suited for aquariums with medium to high lighting, CO injection, or dense plant mass. It ensures your plants receive all essential nutrients without the need for multiple separate products.
It can also be used in simpler setups with adjusted dosing.

For optimal results, use Masterline II as part of a complete aquarium system:
- Masterline Carbo to provide a carbon source for plant growth
