A Comprehensive Guide for the Planted Aquarium

Seachem Flourish:

Seachem Flourish is a comprehensive plant supplement designed for the planted freshwater aquarium. It provides a wide range of essential microelements, trace elements, and other nutrients crucial for the healthy growth and vibrant colour of aquatic plants. Unlike some other plant fertilisers, it is a non-nitrogenous and non-phosphorus-based product, which means it helps to prevent the excessive algae growth often associated with high levels of these nutrients.

What’s in the Bottle?

Flourish is a nutrient-rich formula containing a blend of key elements that are often deficient in an aquarium setup. It is particularly valued for its supply of iron (Fe), which is vital for chlorophyll production, and manganese (Mn), which plays a role in photosynthesis. Other important components include:

• Magnesium (Mg): A central component of the chlorophyll molecule.
• Calcium (Ca): Important for cell wall structure and growth.
• Zinc (Zn), Copper (Cu), and Molybdenum (Mo): Essential trace elements that support various metabolic processes in plants.

The product’s formulation is designed to be easily absorbed by both the leaves and the roots of aquatic plants, making it a versatile addition to any planted tank, regardless of the substrate.

How and When to Use Seachem Flourish

Proper dosing of Seachem Flourish is key to its effectiveness and to avoiding potential issues. The standard recommended dose is 5 ml for every 250 litres (about 66 US gallons) of aquarium water. This should be added once or twice a week, depending on the density of your plants and their nutritional needs.

• Initial Setup: You can begin dosing Flourish from the very start of a new tank setup to give your plants a strong foundation.
• Water Changes: It is beneficial to add a dose of Flourish after each water change to replenish the nutrients that have been removed.
• Monitoring Plant Health: The best way to know if your plants need more or less Flourish is to observe them. Signs of nutrient deficiency include:
  • Yellowing leaves (chlorosis): Often a sign of iron deficiency.
  • Stunted growth or brittle stems.
  • Pale or translucent leaves.

Common Questions and Best Practices

1. Can I use Flourish with other fertilisers? Yes, Flourish is designed to be part of a comprehensive plant care regime. Many aquarists use it in conjunction with other Seachem products, such as Flourish Excel (a carbon source), Flourish Potassium, and Flourish Iron, to provide a complete macronutrient and micronutrient profile.
2. Will it cause an algae problem? Flourish itself is unlikely to cause a significant algae bloom. Since it contains no nitrogen or phosphorus, it does not fuel the type of algae growth that typically plagues aquariums with excess waste or fish food. However, as with any nutrient addition, it’s important to monitor for signs of algae and adjust your dosing schedule and other tank parameters (lighting, CO2) accordingly.
3. Is it safe for fish and invertebrates? Yes, when used as directed, Seachem Flourish is completely safe for all freshwater fish, shrimp, and other invertebrates. The low concentration of metals is harmless to tank inhabitants but beneficial to plants.
4. How should I store it? Store Flourish in a cool, dark place, away from direct sunlight. The bottle should be tightly capped to prevent evaporation and maintain the stability of the nutrients.
