Masterline I

Essential micro nutrients for healthy, vibrant plant growth

Masterline I is a premium micro nutrient fertiliser designed to provide your aquarium plants with all the essential trace elements they need for strong, balanced growth. It plays a crucial role in maintaining vibrant colours, healthy leaves, and overall plant vitality in planted aquariums.

Available in multiple sizes, Masterline I is suitable for both beginner setups and advanced aquascapes.


Available sizes

  • 200ml
  • 500ml
  • 1000ml
  • 5000ml

Choose the size that matches your aquarium needs, whether you are maintaining a single display tank or multiple systems.


Why micro nutrients matter

While macro nutrients like nitrogen and potassium are important, plants also rely on trace elements in smaller amounts to function properly. Without them, plants can develop deficiencies, poor coloration, and slow growth.

Masterline I provides:

  • Iron (Fe) for rich, vibrant colours
  • Trace elements for balanced development
  • Support for healthy leaf structure
  • Improved overall plant health

Ideal for all planted aquariums

Masterline I is suitable for both low-tech and high-tech aquariums. It can be used on its own or combined with other fertilisers depending on your setup.

For tanks with higher plant demand, it is best used alongside a full fertilisation system.


Designed to work with the Masterline range

For optimal results, use Masterline I as part of a complete nutrient system:

  • Masterline II for full macro and micro nutrition
  • Masterline Carbo to provide a carbon source for plant growth
  • Masterline Root Caps for substrate feeding
  • Masterline Safe Water for water conditioning
  • Masterline Crystal Clear for maintaining water clarity

By combining water column feeding with substrate nutrition and proper conditioning, you create a stable and thriving environment for your plants.


Easy to dose

Add the recommended daily or weekly dose directly into your aquarium. Consistent dosing will help maintain stable nutrient levels and promote steady plant growth.

For best results, pair with a dosing pump for accurate and repeatable application.
