JBL Mousse CombiBloc II CristalProfi e4/7/902

Aquarium filtration is essential to maintain clear and healthy water.
In order to retain animal droppings and plant or food residues that pollute the water and become toxic for its inhabitants, we advise you to regularly clean or change the JBL filter media of your JBL CristalProfi external filter .

JBL CombiBloc II CristalProfi e 4/7/902 is a replacement filter mass set for the JBL CristalProfi e402, e702 and e902 filters.

Filter foams are also not eternal. When they have been washed frequently, they no longer remove impurities properly and the water becomes polluted. It is therefore recommended to replace the filter sponges from time to time (frequency unfortunately impossible to define precisely).
Hint: replace after ten washes.
