JBL Blue Foam 50x50x5cm - Fine Grain (30ppi)

50x50x5cm Blue Reusable Fine Mesh Aquarium Filter Foam - Square.
This open-pore blue is manufactured using a special high-pressure process.
Excellent neutral filtration material for freshwater and saltwater aquariums.

The advantages of JBL Blue Foam Sheet 50x50x5cm - Fine Grain:
• Fine grain to retain impurities suspended in water
• Open-pore synthetic foam manufactured using a special high-pressure process.
• Can be cut to any size.
• Neutral filtration material for fresh and sea water.

Easy to use:
Cut a piece of foam 1 to 2 mm larger than the filter cross-section and place it in the filter at the last filtration level. Avoid gaps between the inner wall and the filter.
This fine-pored foam is for use as a pre-filtration or long-term filtration media.

Fine filtration:
The high fineness of the material allows extremely fine particles from 1/1000th of a millimeter to be filtered. Floating algae and the finest turbid matter can be removed from the water in record time.

Safe to use:
Neutral foam that does not release any harmful substances into the aquarium. Open pores obtained by a special high-pressure process.

Foam quality:
Foams used in the presence of live animals must be strictly tested, as most synthetic materials release problematic plasticizers into the water. All plastics used by JBL have undergone this test and do NOT release any harmful substances into the water.

Cleaning plastics:
For many months, it is sufficient to rinse the dirty filter foams under lukewarm running water and then inoculate them with filter bacteria before restarting (JBL FilterStart).
However, since mechanical cleaning NEVER allows for complete cleaning and dirt remains in the foam, it is recommended to replace the foams approximately every 6 months.
