Tropica Premium Nutrition is a premium liquid aquarium fertilizer. It is formulated specifically for tanks with a high fish stock and few or slow-growing plants. Because fish waste and uneaten food naturally supply nitrate and phosphate, this formula intentionally contains no nitrogen (N) or phosphorus (P). As a result, it helps prevent nutrient overload and aggressive algae blooms.

Key Features and Ingredients:

• Targeted Micronutrients: Loaded with iron, manganese, magnesium, and essential trace elements that plants absorb directly through their leaves.
• Potassium Boost: Contains potassium to promote robust root development and prevent the yellowing of older leaves.
• Algae Prevention: Starves potential algae by leaving out unnecessary macronutrients while ensuring plants stay healthy and competitive.
• Invertebrate Safe: Contains only trace amounts of copper, making it completely safe for sensitive shrimp and snails.

Dosing Instructions:

You should add Premium Nutrition once a week immediately after a water change.

• Standard Dosage: Use 6 mL per 50 Litres of aquarium water weekly.
  • Adapt dosage to amount of plants in the aquarium.
• The Pump Advantage: Standard 125ml and 300ml bottles feature a calibrated pump where 1 press = 2 mL. This equals exactly 3 pumps per 50 Litres.
• Maintenance: Pair this routine with a minimum 25% – 70% water change every week to prevent nutrient imbalances.

Premium vs. Specialised Nutrition:

If your aquarium has a heavy plant biomass, fast-growing stem plants, or intense lighting and CO2, plants will likely deplete macronutrients faster than fish can produce them. In those setups, consider switching to Tropica Specialised Nutrition 125ml which includes the missing nitrogen and phosphorus.
