Product information

Easy to use
Cut foam about 1-2 mm larger than the relevant cross section of the filter and put it into the filter as the last filter stage. Avoid gaps between the inner wall and filter. Coarse-pored foam as long-term filter material.

Fine filtering
The fine material filters even the smallest particles (1/1000 mm upwards) out of the water. This removes floating algae and very fine turbidity from the water almost immediately.

Absolutely safe
No release of pollutants into the water thanks to neutral foam. Open-pored through dedicated high-pressure treatment.

Quality of foam:
Foams used in aquaristics with live animals must always be subjected to a pollutant test, as most plastics release problematic plasticisers into the water. All the plastics used by JBL have passed this test and do NOT release any harmful substances into the water.

Cleaning of plastics:
For many months it is sufficient to rinse the dirty filter sponges under lukewarm running water and then inoculate them with filter bacteria (JBL FilterStart) before using them again. However, as mechanical cleaning NEVER leads to complete cleaning and dirt will remain in the filter sponge, it is recommended you replace the filter sponges about every 6 months.

Inoculating filter material with cleansing bacteria: Initial colonisation of filter material with cleansing bacteria takes about 1-2 weeks in freshwater and twice as long in seawater. If the filter material was already in use, the time for a "recolonisation" is doubled, as recolonisation does not take place so easily on dead bacterial lawns. The addition of concentrated cleaning bacteria such as in JBL FilterStart shortens the biological start-up time to about 24 hours. Another reason is to fill the existing settlement space in the filter material with beneficial bacteria so that pathogenic germs find no place to spread. This has now been scientifically proven.

FAQ
What helps with green water in the aquarium?

Green water means floating algae, which grow when they have no competition from other plants and, even more, when the excrement of the fish creates excessive nutrient pollution in the water. The filter will not be able to do much about this. Ultimately, there are only two options:

1. Carry out significantly more water changes in order to remove the nutrients caused by fish excrement.

2. A JBL PROCRISTAL UV-C Compact plus kills off the floating algae.

A temporary measure is to switch off the light for 2-3 days in order to stop photosynthesis in the algae.
