Product Description
The Juwel fine or Coarse filter sponge is primarily used for the biological filtering of your aquarium, making it an essential component of the Juwel filter system.
The fine pore structure gives a very large surface area, guaranteeing slow and even water flow conditions. This means that it is particularly suitable for biological filtering in the aerobic area.
The coarse pore structure gives a large surface area, guaranteeing relatively high and even water flow velocity. This means that it is particularly suited to biological filtering in the aerobic area.
The open pores of the Juwel filter sponge were made without the use of chemicals, meaning that there is no residue.
• Optimum biological filtering characteristics
• Homogeneous structure, guaranteeing even flow conditions
