## Long description

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.
