eSHa Aquabacter contains natural bacteria cultures to create and support the biological balance in the aquarium. The biological balance is the ideal of every true aquarium enthusiast. When your aquarium is in good natural balance, biological waste products such as excreta, food and plant debris are composted and reused. You get a healthy aquarium with clear water and beautiful plants, where algae get few chances. This natural balance is maintained by bacteria. These bacteria break down pollutants such as excrements and convert them into nutrients for plants. By adding eSHa Aquabacter, the processes of waste decomposition and nitrification are quickly set in motion. Without this addition, it will take about two months for these cycles to work properly. Especially in the beginning, your aquarium will be a little more sensitive than usual anyway. A temporary imbalance in existing aquariums will be rebalanced by the maintenance dosage.eSHa Aquabacter is used in existing and new aquariums.
