Essential carbon supplement for vibrant, healthy planted aquariums.
Waterbox Carbon+ delivers a highly absorbable liquid carbon source that promotes lush plant growth, vibrant coloration, and a balanced aquarium ecosystem. Maintaining proper carbon levels is essential for supporting photosynthesis, improving nutrient uptake, and reducing nuisance algae in freshwater planted aquariums.
Carbon+ is ideal for aquariums that do not utilize a CO₂ injection system, providing an efficient alternative carbon source for aquatic plants. It can also be used in systems with CO₂ supplementation when additional carbon dosing is required for enhanced growth and stability.
Key Benefits:
• Supplies a readily available carbon source for aquatic plants
• Promotes strong growth, color, and overall plant health
• Helps reduce unwanted algae through nutrient balance
• Supports photosynthesis and nutrient absorption
• Effective for both CO₂ and non-CO₂ planted aquariums
Directions for Use:
Use 1 ml per 100 L (25 gal) of aquarium water daily.
For heavily planted or high-demand aquariums, dosage may be increased up to twice the standard rate.
