Eheim Synth: filter wool for fine cleaning.
Contents: 1 L + 5 L
These fine filter wool clean the water before it enters the aquarium, so as the last filter layer, once again mechanically. Eheim Synth extracts fine particles from the water, which are often responsible for cloudiness in the water. As a final filter layer, Eheim Synth is used in a thin layer of 1-2 cm. Always use a new layer of Eheim Synth after drug treatment.
