Cleaning the EasyCrystal FilterBox
Procedure:
Fig. G
1. Dismantle the device in the sequence shown in the diagram.
– Clean soiled parts with water or a special cleaner for
aquariums. Other cleaning products may harm the crea-
tures and plants in the aquarium.
– Check the BioFoam filter foam. If it is clogged up, it should
ideally be washed in skimmed aquarium water to retain
beneficial bacteria.
– Clean out the biological filter balls with lukewarm water.
2. Reassemble the device in reverse order.
