Easy-Life Easy Carbo Bio is a natural liquid carbon source for aquarium plants on a natural basis. Carbon is important for plants to grow well and compete effectively with algae. With too little carbon or CO2 in the aquarium, algae often get a chance. Carbon (in the form of CO2 dissolved in the water) is one of the most important nutrients for optimal plant growth. If there is a lack of carbon, plants are not able to optimally assimilate and grow. As a result of this deficiency, plants stop growing and no longer compete with algae for the nutrients. If this carbon deficiency lasts for too long, then plants start to leak sugars and other nutrients which attract algae. As a result, leaves become covered in algae and look unattractive. For use in aquariums with or without additional CO2 fertilization. Safe for all aquarium inhabitants such as fish, shrimps and snails.Dosage Easy-Life Easy Carbo BioAdd weekly 10 ml per 100 litres of aquarium water
