Dennerle's Dosator is a marvelous tool for anyone with a planted aquarium. It provides constant and consistent nutrient dosing in the aquarium without electricity or moving parts.

The Dosator leverages the principle of osmosis to move aquarium water through the unit and thereby mixing and diluting your fertilizer of choice with aquarium water. Osmosis then moves this diluted mixture up the Dosator's riser tube and enters the aquarium a drop at a time, at a constant rate. The various colors of Dennerle's liquid supplements work with the Dosator to provide a visual refill indicator. When the water inside the Dosator's chamber is absent color, then it is time to add more nutrients; simple! Suitable for aquariums 10 to 80 gallons.
