Specifically designed for Fluval 106/206 and 107/207 external filters, Bio-Foam + foam blocks work extra hard by acting as an effective filter media for both mechanical and biological filtration.
Key features:
- Provide mechanical and biological filtration;
- Have a large porous surface that supports the expansive proliferation of beneficial (nitrifying) bacteria;
- Effectively trap small particles and debris, especially those not retained by the foam during the first stage of filtration;
- Are custom-fitted specifically for 06 and 07 series filters to increase filtration efficiency;
- Help create a healthy aquatic environment and ideal water conditions;
- Should be rinsed every 3 months;
- Should be replaced every 6 months;
- Suitable for fresh and saltwater aquariums.
