Coarse Filter Sponge The Juwel filter sponge coarse serves for the mechanical and biological filtering of your aquarium, making it an essential component of the Juwel filter system.
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.
Suitable for both freshwater and marine aquariums.
These pads should be changed out every 3 months as it is the first step in the biologicial filtration.
There are 3 sizes of filter media to suit the different filters.
For models Rekord 600, 700 and 800 using the Bioflow Super Filter system, the ompact size media is used. Exception is the poly pad and carbon that use a super compact model which are slightly smaller than the standard compact media.
For the New Vio 40 model aquariums with the Bioflow Mini Filter system, These take a single compact coarse sponge.
Juwel Filter Media ensure optimum water conditions to make your fish and plants healthy and vibrant.
