FEMANGA Carbo - Active 500ml liquid carbon supplement for aquariums, 500 ml

FEMANGA Carbo - Active 500ml is a liquid carbon supplement formulated for planted freshwater aquariums. Supplied in a 500 ml bottle, this concentrated organic carbon source is designed to support aquatic plant growth in setups where CO2 injection is not available or as a supplemental carbon feed alongside gas injection. The product is intended for routine dosing to assist plant metabolism, enhance nutrient uptake and help reduce algae problems linked to insufficient available carbon.

Advantages

FEMANGA Carbo - Active provides a soluble, immediately available form of organic carbon that can be added directly to aquarium water. It is concentrated for economical dosing and compatible with standard liquid fertilizer regimes. Using a liquid carbon supplement can help stabilize plant growth in tanks without pressurized CO2 systems and can act as a complementary carbon source in systems with CO2. The formulation is intended for freshwater planted aquaria and for supporting balanced nutrient uptake by plants.

Suitable for

• Planted freshwater aquariums without CO2 injection
• Aquaria where CO2 injection is supplemented with liquid carbon
• Community tanks with moderate light and regular fertilization
• Maintenance programs aimed at reducing algae caused by carbon deficiency

Key specifications

• Form: concentrated liquid solution
• Volume: 500 ml bottle
• Intended use: organic carbon supplementation for aquatic plants
• Application: direct dosing into aquarium water
• Compatibility: formulated for freshwater planted systems

How to use

Shake the bottle before use. Dose according to aquarium volume and the manufacturer’s recommended schedule, introducing the liquid carbon into the water column away from filters or direct flow to promote even dispersion. Adjust dosing based on plant response, water parameters and the presence of other fertilizers or CO2. Monitor plants and algae levels after starting treatment and reduce or stop dosing if adverse effects occur or if dosing overlaps with other carbon sources.

Usage recommendations

Start with conservative dosing and observe plant growth and algae development for one to two weeks. Combine FEMANGA Carbo - Active with a complete fertilization plan tailored to your aquarium’s light level and stocking. Regular water testing and partial water changes help maintain stable conditions when using liquid carbon supplements.
