Round sponge No. 6, coarse, 12 x 12 x 20 cm, blue

Round sponge No. 6, large -porous - designed for the aquarium filter, is an important part of the filtration system. It plays the role of a mechanical filter, delaying large particles of dirt and food remnants, preventing them from entering more complex filtration materials.

The large -porous structure allows you to effectively delay large particles of dirt, without clogging too quickly. It also has good bandwidth for water, which allows maintaining normal circulation in the aquarium. It is necessary to correctly install it in the cassette or compartment of the filter.

It is important to periodically check the condition of the sponge and clean it. Hole diameter - 13 mm.
