Automated daily fertilization for aquarium plants

For 50 to 300 liters aquarium

With the Dosator, your aquarium plants are fertilized as in nature, in that they are given a small quantity of nutrients on an ongoing basis

The dosator is specially designe for the Dennerle fertilization V30 complete and S7 VitaMix. V30 is dispensed automatically over 4 weeks; S7 over the space of 1 week.

-How it works-

The Dennerle Dosator made from high-quality plastic works according to the principle of osmosis. Water from the aquarium "seeps" through the semi-permeable special membrane into the reservoir, pushing the nutrient solution drop-by-drop via the riser into the aquarium. This has two effects: firstly the aquarium gets the amount of fertilizer it needs, and secondly: the Dosator becomes a "tank indicator": as the water enters bit by bit and pushes the fertilizer into the aquarium, the fertilizer-water mixture in the Dosator becomes increasingly clear. When the contents of the dispenser lose their color (S7 orange, V30 yellowy-green) you know it is time to fertilize.
