2025
The Dennerle Plant System Set is a sophisticated three-component fertilizer system for healthy, vibrant, and colorful aquarium plants. Based on the original concept from 1980, it combines decades of experience with modern liquid dosing and a clearly structured care plan.
2006 - 2008
2006 marks the refinement of the proven concept—clearly structured care routines and a more precise, everyday-practical system. 1980 marks the launch of the Plant System Set—the moment when experience became a reliable principle: separate nutrient applications for reproducibly healthy plants.
2008
From miniature to magic: shrimp, snails, miniature aquascapes – small biotopes, big fascination. Today, more precise, more sustainable, closer to nature than ever before.
1980
In many aquariums, plants grew very poorly or were plagued by unsightly algae infestations. Based on decades of experience in cultivating aquarium plants, Dennerle began to develop a system that would ensure success for everyone and make the aquarium trouble-free and algae-free.
1966
A man kneels in a tropical stream, stroking leaves, noting colors, currents, and light. Ludwig Dennerle listens to the stories of aquatic plants – patiently, leaf by leaf. Curiosity becomes method, and method becomes a vision: to understand nature, preserve it, and bring it home. Thus, Dennerle is born – from wet boots, notebooks, and a love of living plants.
FAQs
What is the difference between the regular and the Nano set?
The Nano Set is for aquariums up to 100 L and uses dropper bottles for fine dosing. The Standard Set has dosing caps for aquariums larger than 100 L.
How often do I need to fertilize?
Every week: S7, E15 mid-month, V30 at the end of the month. A clear plan for everyone.
Is the system also suitable for beginners?
Yes, it is easy to use and avoids typical mistakes such as over-fertilization.
Can I combine the system with soil?
Yes, it harmonizes with active soils and supports nutrient replenishment.
Is the system shrimp-friendly?
