Every aquarium is a complex biological system whose components are intertwined and influence each other. Creating a stable, natural balance between these components is the aim of every true aquarium enthusiast. The Dennerle Balance System helps you control each element easily and safely while achieving  a good balance. 

Since Dennerle‘s founding in 1966, we have been cultivating a holistic view of the aquarium ecosystem. We strive to reproduce the biological cycles that occur in nature, in the home aquarium. We have identified the following five vital elements that influence the biological system inside your tank: animals, water, light, substrate, and plants. This is the point from which our product development starts, resulting in a system of fine-tuned products, that help you create underwater worlds, which can be easily and safely maintained. This is all you need to achieve balance in your aquarium, and to enjoy a fascinating  piece of nature in your living room!
