About this product

MasterLine II — Concentrated Macronutrient Formula

Built for high-demand planted tanks. MasterLine II delivers a concentrated blend of Nitrogen, Phosphorus, Potassium, and Magnesium — the four essential macronutrients for healthy, harmonious plant development in fast-growing, densely planted aquariums.

Key Features

  • N, P, K & Mg — complete macronutrient coverage in a single formula
  • High-demand formulation — designed for Dutch-style tanks and aquariums with dense planting and fast growth
  • Precision dosing — ideal for aquarists who dose macro and micro nutrients separately for full control
  • Promotes harmonious growth — balanced macros support even development across all plant species
  • 500ml — concentrated for long-lasting use

Pair with MasterLine I (micronutrients) for a complete two-part dosing system tailored to your aquascape's exact needs.
