Juwel BioPlus Fine Filter Sponge Bioflow 8.0 for Aquarium
The JUWEL fine filter sponge is primarily used for the biological filtering of your aquarium in the anaerobic zone, 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 anaerobic area.
The open pores of the JUWEL filter sponge were made without the use of chemicals, meaning that there is no residue.
It is recommended to change the bio plus Fine sponge every 3 to 9 months to keep your filter running as efficiently as possible.

The sponge works well in my 100-liter freshwater tank. Water flow is smooth and the filter maintains good water quality over time. I’ve used it for 6 months and it’s still performing well.

I noticed a significant improvement in water clarity after installing this sponge. It’s easy to clean and doesn’t clog easily. I plan to keep it for another 3 months before replacing.

No chemical smell or residue after installation. The sponge holds up well in the anaerobic zone and supports beneficial bacteria growth. My fish seem more active now.

It fits well in my filter, but I had to adjust the placement slightly. Performance is good, but I expect better flow control in larger tanks.
