Dosator Dosage Rings/Membrane DE-DOSR
This package contains six sheets with six adhesive rings each, six membranes, and instructions. With a Dosator, your aquarium plants are nurtured as they would be in their native environment, in that they are constantly provided a small amount of nutrients.
The Dennerle Dosator employs the principle of osmosis with semi-permeable membranes that allow aquarium water to seep through into the reservoir, pushing the nutrient solutions drop by drop via the riser into the tank. The Dosator is best paired with the Dennerle fertilizers V30 Complete and S7 VitaMix. Dosage rings are stuck to the membrane to control the amount of CO2 that enters your Dosator reservoir.
