Seachem Flourish Excel is a liquid source of bioavailable organic carbon, essential for the health and growth of aquatic plants. While CO2 injection is a common way to provide carbon, Flourish Excel offers an alternative or complementary solution by delivering organic compounds that plants can readily use in the photosynthesis process. This product also has iron-reducing properties, converting iron into a form that plants can absorb more easily, further enhancing their growth and vitality.

Key Features:

• Bioavailable Carbon Source: Provides essential organic carbon for aquatic plants, either as an alternative to or in addition to CO2 injection.
• Supports Photosynthesis: Introduces compounds that are structurally similar to photosynthetic intermediates, making carbon uptake more efficient.
• Iron-Reducing Properties: Converts ferric iron (Fe+3) to ferrous iron (Fe+2), which is more easily utilised by plants.
• Balances pH Risks: Ideal for use in aquariums where continued CO2 injection may cause dangerously low pH levels.

Why It's Different: Flourish Excel bypasses the traditional CO2 pathway by providing a carbon compound similar to those created during photosynthesis. This allows plants to utilise it directly in building longer carbon chains required for growth, simplifying and accelerating the process.

Directions for Use:

1. Initial Use: After a major (> 40%) water change, dose 1 capful (5 mL) per 40 L (10 gallons) of water.
2. Maintenance Dosing: Add 1 capful (5 mL) per 200 L (50 gallons) daily or every other day.
3. High-Growth Aquariums: Gradually increase dosing for tanks with fast-growing plants.
4. For smaller tanks, each cap thread equals approximately 1 mL, allowing precise dosing.

Available Sizes:

• 100 ml
• 250 ml
• 500 ml
• 2L
• 4L

Seachem Flourish Excel provides an efficient way to supply carbon and promote healthy plant growth, ensuring your aquarium plants thrive with or without a CO2 injection system.
