JBL Cristalprofi Combibloc II - Set of prefiltration inserts and filter foam for CristalProfi e 402/702/902 filter

Foam quality
Foams used in the presence of live animals in the aquarium must absolutely have been tested for harmful substances, because most synthetic materials release problematic plasticizers into the water.

All plastics used by JBL have undergone this check and release NO harmful substances into the water.

Cleaning of plastic materials
For many months, it is sufficient to rinse dirty filter foams under lukewarm running water and then inoculate filter bacteria before restarting (JBL FilterStart).

However, as mechanical cleaning NEVER allows total cleaning and dirt will remain in the foam, it is recommended to replace the filter foams approximately every 6 months.

Leave a filter foam that you have just cleaned overnight in a glass of clean water and the next morning, you can smell the amount of dirt still contained in the supposedly clean foam!

Inoculation of cleaning bacteria into the filtration material
A first colonization of the filtration material by cleaning bacteria lasts approximately 1 to 2 weeks in fresh water, twice as long in sea water.

If the filtration equipment was already in use, the time for a "recolonization" will be multiplied by two, because it is not so easily done on a dead bacterial mat.

The addition of concentrated cleaning bacteria as in the JBL FilterStart reduces the biological break-in period to approximately 24 h.

Another reason for this addition is to fill the colonization space with these useful bacteria so that possible pathogenic germs find no place to spread.

This has now been proven scientifically.
