sera Flore 1 Carbo - Anti-Algae & CO2Prohibits algae and additional carbon (CO2) for optimal growth Systemic care Alternative carbon source For aquarium plants Plants require carbon for doing photo synthesis, which often is not available in the water in sufficient amounts. Lacking carbon is one of the most important growth limiting factors for aquatic plants. The new systemic plant care sera flore 1 carbo was developed for providing the plants the amount of carbon required for optimal
