About Dennerle

Nature is full of wonders. It teaches us the laws of biological balance. It develops amazing solutions to complicated problems. This is Dennerle’s guiding principle.

More than fifty years ago, Ludwig Dennerle’s love of aquaristics and interest in a hitherto little-known profession drove him to research aquatic plants and is the impetus for us to inspire others for the aquatic world – true to the motto: Experience nature.

Experience nature since 1966!

Every aquarium is a biological system whose individual elements influence each other. The harmonious interaction of the 5 elements makes the aquarium the natural underwater world that you want.

Since the company was founded in 1966, we at Dennerle have taken a holistic view of the aquarium ecosystem in order to recreate the biological cycles within it as faithfully as possible. There are 5 elements that significantly influence the system: Animals, plants, water, substrate and lighting. This is where our product development comes in. The result: a system of optimally coordinated products with which you can design and set up your underwater landscape entirely according to your wishes and maintain it easily and safely. That’s all you need.

Aquarium in balance: a fascinating and intact piece of nature.

Research and development

Without our own research, there can be no real innovations. That is why the Dennerle research department is the creative heart of our company. This is where the latest scientific findings meet many years of experience from all areas of aquaristic practice.

We start researching where others stop!

To ensure that this remains the case in the future, Dennerle is constantly breaking new ground. In collaboration with microbiologists, chemists and botanists, who can do more than simply combat symptoms. Our aim is to positively influence biological processes right from the start, so that we can live up to our claim: Experience nature.
