Colouring

All Dennerle Quartz gravel types are coloured exclusively with natural or nature-identical iron oxides. These pigments provide a long-lasting, color-stable, and natural appearance that does not fade even under intense lighting or CO₂ fertilization. Our iron oxides are not water-soluble under normal aquarium conditions and are completely safe for all aquarium inhabitants.

Dennerle

Dennerle has been operating in Vinnigen since its foundation in 1966 and, after more than 50 years of company history, the building blocks Dennerle relies on is experience. The philosophy behind Dennerle is to create a small and tangible, intact piece of nature, in harmony with the natural environment. That is why sustainability is a company-wide concept and is implemented at every possible point.
