Easy Carbo 250ml Easy Carbo is an extremely powerful & effective carbon source for aquarium plants. It also actively combats & prevents the growth of algae. 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 & grow. As a result of this deficiency, plants stop growing & no longer compete with algae for the nutrients. If this carbon deficiency lasts for too long, then plants start to leak sugars & other nutrients which attract algae. As a result, leaves become covered in algae & look unattractive. Easy Carbo is the solution to this problem. After Approx. two weeks of using Easy Carbo, plants visibly grow better & look better. This is particularly true of swamp plants (Cryptocoryne sp., Echinodorus sp., etcetera). As a result of the increased competition for nutrients, algae find it very difficult to survive &, in most cases, they disappear altogether.. The use of Pro Fito & Easy Carbo is the right combination. Plants require more than just carbon. Trace elements are also essential. Since their presence cannot be precisely measured & we, therefore, do not know which trace elements are present in the water, Pro Fito is the ideal solution to enrich water with trace elements in the most complete way.
