VII. MAINTENANCE
Regular maintenance should be carried out in order to guarantee the normal operation of the accessories and the correct
biochemical balance of the water. In the NEWA More aquarium, these operations are extremely easy and can be carried out
without soiling or wetting any furniture or furnishings. All you need is a container in which to put the material extracted from
the aquarium and a paper/fabric towel.

VII.a CLEANING THE ROTOR

To clean the rotor and the pump impeller, follow the instructions given below:
1. WARNING: disconnect the power supply from all electrical appliances operating in the aquarium. If installed, leave the heater

to cool for at least 15 minutes before proceeding with the next steps.
2. Remove the skimmer collection cup from its position, as well as the filter compartment lid and the Mechanichem More and
Biofoam More filter cartridges (when present). Put them all in a container.
3. Ease out the corner cable housing profile from its position, using the lever on the corner of the
Newa More filter (Fig. 28).
4. Take out the Newa More filter from its position and put it on a paper/fabric towel, placing it on its side (Fig. 29).
5. Access the magnetic rotor, separating the impeller chamber from the pump housing.
6. Remove the magnetic rotor using a pair of tweezers. Clean the magnetic rotor and the impeller chamber with a brush under
running water. If there are any scale deposits, place it in a vinegar solution for 15-20 minutes before cleaning. Then rinse
thoroughly.
WARNING: do not use acids or solutions other than normal vinegar for food use, as they might be toxic to fish.
7. Carefully put the magnetic rotor back in the pump, closing it with the impeller chamber. Put the Newa More filter and any
other component back into place (see Chapter V, paragraph b, steps 5 and 6), in reverse order.

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

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.
