The innovative Dosator is designed to simplify and optimise the fertilisation with V30 Complete and S7 VitaMix from the Dennerle ferilisation system. The automatic, steady application of fertiliser in form of drops comes closest to a natural, permanent supply to the plants. Through this way of dosing - in contrary to the common push fertilisation - the nutrient supply constantly remains in the optimal area. This method simultaneously prevents algae growth by nutrient imbalances.
The Dosator is made to provide aquarium tanks of 50 to 300 litres with fertiliser. Through the inbuilt semi permeable membrane, aquarium water gets pulled into the Dosator's fertiliser reservoir by osmosis. Then, this water pushes the fertiliser through the integrated riser pipe drop by drop into the aquarium. This specifically invented technique immensely differs from other dispensing aids which usually are electrically operated and, therefore, are less ecological or still base on daily push fertilisation. This evenly small addition of fertiliser keeps the nutrient flow constant without any further technique and cares for healthy and strong plant growth.


  • Innovative fertilisation with the physical principle of osmosis
  • Works without any further technique
  • Keeps nutrient flow permanently constant
  • For V30 Complete and S7 VitaMix
  • Prevents algae growth
  • Cares for healthy and strong plant growth
  • Consists of durable plastic material


With the Dennerle Dosator the V30 Complete is dosed automatically over the period of 4 weeks.
The automatic supply of the S7 VitaMix takes place over the time of 1 week.
After these periods the Dosators need to be refilled. For the Dennerle fertilisation system, two Dosators are needed!



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.

Dennerle offers the optimum equipment to bring this complex, but not complicated system into harmony.
