Seachem Flourish Excel 500 ml – Liquid Carbon Source for Aquatic Plants & Algae Control

Description

Seachem Flourish Excel 500 ml – Liquid Carbon Source for Aquatic Plants & Algae Control.

Seachem Flourish Excel 500 ml is a premium, biologically available liquid carbon supplement specially formulated for all planted aquariums. It provides an essential carbon source for aquatic plants, enabling them to perform photosynthesis efficiently even in tanks without CO₂ injection. In addition to stimulating plant growth, Flourish Excel helps control nuisance algae by limiting its carbon access and promoting strong, healthy plant competition.

Carbon is the backbone of all organic life, and in a closed aquarium system, it is often the limiting factor that prevents lush plant development. Flourish Excel™ bridges this gap by delivering a readily assimilable organic carbon compound that plants can use directly. Whether you maintain a low-tech planted tank or a high-energy CO₂ system, Flourish Excel works seamlessly to enhance coloration, increase leaf density, and accelerate new growth.

Unlike many liquid carbons, Seachem’s formula is scientifically stabilized, ensuring safe and gradual carbon release without harming fish, shrimp, or beneficial bacteria. It also aids in the breakdown of ferrous iron (Fe²⁺) to ferric iron (Fe³⁺), making vital micronutrients more accessible to plants.

Key Features & Benefits:

• Provides Bioavailable Organic Carbon – Supplies a direct carbon source usable by all aquatic plants.

• Enhances Photosynthesis & Growth – Promotes lush, vibrant leaves and faster plant metabolism.

• Reduces and Prevents Algae – By supplying carbon to plants, Flourish Excel deprives algae of its essential energy source.

• Safe for All Aquariums – Completely non-toxic to fish, shrimp, snails, and other aquatic life.

• Supports CO₂ Injection Systems – Acts as an additional carbon supplement or a stand-alone alternative.

• Improves Nutrient Uptake – Helps plants utilize trace elements and minerals more efficiently.

• Prevents Melt in New Plants – Particularly beneficial during the initial setup or after major water changes.

• Promotes Algae-Free Environment – Encourages healthy plant competition to naturally suppress algae.

How It Works:

Flourish Excel contains a stabilized form of organic carbon known as glutaraldehyde polymer derivative. When dosed into the water, it converts into intermediate compounds that plants can assimilate directly during photosynthesis. This process boosts energy production, supports faster root development, and stimulates lateral growth in stems and leaves.

Because algae also rely on dissolved inorganic carbon (CO₂) for photosynthesis, supplying plants with an alternative organic carbon source gives them a competitive edge - out-competing algae naturally rather than relying on harsh algaecides.

Directions for Use:

• On initial setup or after major (>40%) water change:
  → Use 1 capful (5 mL) for 40 L (10 US gallons).

• Thereafter for daily maintenance:
  → Use 1 capful (5 mL) for 200 L (50 US gallons) daily or every other day.

• For smaller aquariums, use the threaded cap marks as measurement (1 mL each line).

Tip: Always dose Flourish Excel during the light period to maximize plant uptake and efficiency.

Compatibility:

• Safe for freshwater planted tanks, shrimp aquariums, and community fish setups.

• Can be used with Seachem Flourish Comprehensive™, Flourish Iron™, Flourish Trace™, and Flourish Potassium™ for a complete nutrient regimen.

• Compatible with CO₂ systems or can be used as a stand-alone carbon source in low-tech setups.

---

Ingredients:

Proprietary solution of bioavailable organic carbon compounds, stabilized glutaraldehyde polymer derivative, deionized water, and chelating agents for nutrient stability.

---

Application Scenarios:

• Low-tech planted aquariums that lack pressurized CO₂ systems.

• High-light aquariums to supplement carbon availability.

• During initial plant setup to reduce “melt” and enhance root anchoring.

• As a preventive measure for algae control and overall water clarity.

---

Expert Tips:

• Avoid overdosing; always start with recommended quantities.

• Combine with Seachem Prime™ for dechlorination and Seachem Stability™ to maintain biological balance.

• Use with a good light source (6–8 hours per day) for optimal plant response.

• Maintain steady water parameters (pH 6.5–7.5, temperature 22–28 °C).
