VII.b REPLACING THE FILTER CARTRIDGES
To maintain maximum performance of filters and ensure the best conditions for the water in your aquarium, it is advisable to
regularly replace the filter cartridges following the times specified in Chapter VI. The Mechanichem and Biofoam filter cartridges
are specifically designed to be replaced with the utmost ease, without having to stop the filter or get your hands wet.
To carry out this operation correctly, proceed as follows:
1. Open the lid of the filtering area and remove the filter cartridges that you want to replace, taking them by the special handle.
Dispose of them in compliance with the regulations in force in the country of disposal.
2. For the Mechanichem More I or II chemical filter cartridge: remove it from its packaging and insert the new filter cartridge
into the filtering department (NMO20/NMO30: make sure that the wording “TOP SIDE”, on the filter cartridge handle, is facing
upwards, Fig. 12).
3. For the Biofoam More biological filter: remove the Mechanichem More filter cartridge, as shown in step 2. Remove the sponge
filter from its packaging and insert it in the support frame. Replace the filter cartridges.
4. Put the lid back on the filtering compartment.
