Dosator

Aquarium plants need a regular supply of nutrients for healthy, strong growth. Aquariums are usually fed in the form of a "shock fertilization," meaning that a large amount of fertilizer is added at regular intervals. With the doser, however, aquarium plants are fertilized just like in nature, as they constantly receive a small amount of nutrients. The advantages at a glance:

• Permanent, consistent nutrient supply as in nature
• Uniform, balanced plant growth
• Prevents algae through lower nutrient levels
• Fertilizing in the optimal range in the simplest way
• Reliable operation, as there are no moving parts and no electricity (instead of a dosing pump)
• Considerably cheaper than a dosing pump
• Made of high-quality, durable plastic
• Developed and manufactured in Germany

The doser is specially designed for the Dennerle fertilizers Plant System V30 (complete fertilizer) and Plant System S7 (vital substances). V30 is dosed automatically over 4 weeks, S7 over 1 week.

AN INNOVATION FROM DENNERLE

The Dennerle doser, made of high-quality plastic, works on the principle of osmosis. Water from the aquarium "migrates" through the semi-permeable special membrane into the storage container, which pushes the nutrient solution into the aquarium drop by drop via the riser pipe. This has two effects: firstly, the aquarium receives the amount of fertilizer it needs, and secondly: the doser becomes a "tank indicator" : as water gradually penetrates and pushes fertilizer into the aquarium, the fertilizer-water mixture contained in the doser becomes clearer and clearer. When the contents of the storage container lose color (S7 orange, V30 yellowish green), you know it is time to fertilize. Aquarium plants benefit from a permanent, even supply of nutrients, just like in nature. This ensures healthy, balanced plant growth and lets the aquarium shine in a magnificent, rich green. Disadvantages due to excessive nutrient levels through shock fertilization are a thing of the past. And best of all: the overall lower nutrient level and the supply of nutrients to the plants according to their needs counteracts excessive algae growth.

The doser with constant fertilization!

The dosator was specially developed for use with Plant System V30 and Plant System S7 as part of the Dennerle fertilization system: V30 is dosed automatically over 4 weeks, S7 over 1 week (2 dosators are required). The innovative fertilizer doser made of high-quality, durable plastic can be used to supply aquariums from 50 to 300 liters. The dosator is also ideal for use with V30 as a sole fertilizer and ensures a consistent, drop-by-drop fertilizer supply over 1 month. Since the dosator works purely according to the physical principle of osmosis and has neither moving parts nor requires batteries or a power connection (like a dosing pump/automatic fertilizer device), it is very reliable and economical. It also offers clear advantages over a classic daily fertilizer, because the device only needs to be refilled once a week (S7) or once a month (V30).
