About this product

MasterLine I — Concentrated Micronutrient Formula

Total control starts here. MasterLine I delivers all the essential micronutrients your aquarium plants need in a single concentrated formula — designed for advanced aquarists who dose micro and macronutrients separately for precise chemistry management.

Key Features

  • Complete micronutrient profile — all essential trace elements for healthy, vibrant plant development
  • Two-part dosing system — pairs perfectly with MasterLine II (macronutrients) for full spectrum nutrition
  • Ideal for Dutch-style tanks — formulated for heavily planted aquariums with fast growth rates
  • Advanced precision — dose independently to fine-tune your tank's exact micronutrient levels
  • 500ml — concentrated for long-lasting use

When off-the-shelf all-in-ones aren't precise enough, MasterLine I gives you the micronutrient control your aquascape deserves.
