Description

MasterLine All In One Golden — Complete Nutrition for Demanding Planted Aquariums

MasterLine All In One Golden is a complete macro- and micronutrient liquid fertilizer developed specifically for planted aquariums with demanding, hard-to-grow plant species. It supplies nitrogen, phosphorus, potassium, magnesium, iron, manganese, zinc, boron, copper, and molybdenum — all in a single bottle, in chemical forms that plants absorb easily.

Why aquascapers choose Golden

  • Healthier root systems — nutrients are delivered in multiple absorbable forms, encouraging stronger root development
  • Thicker leaves and stems — moderate, robust growth rather than leggy, fast growth
  • Faster adaptation for difficult species — ideal for plants that struggle under standard dosing
  • Simplified dosing — one bottle replaces a shelf of single-element fertilizers
  • Safe for shrimp and all aquatic life — trace copper levels formulated with invertebrates in mind

Composition (per 100 ml)

Nitrogen (N) 0.81%
Phosphorus (P) 0.20%
Potassium (K) 2.25%
Magnesium (Mg) 0.6%
Iron (Fe) 0.21%
Manganese (Mn) 0.07%
Zinc (Zn) 0.05%
Boron (B) 0.04%
Copper (Cu) 0.009%
Molybdenum (Mo) 0.006%

Dosing

Daily: 1 ml per 30 L of aquarium water. Shake well before use. Requires supplemental CO₂ injection — without CO₂, plants cannot make full use of the added nutrients. For best results, pair with MasterLine Carbo as a carbon source booster.
