where it leaves coarse deposits and undergoes initial biological treatment. Subsequently, the active carbon and the second layer
of synthetic wool trap any remaining deposits, neutralizing all organic substances that tend to colour the water or create bad
smells. The Mechanichem filter cartridges should be rinsed every 7-8 days under running water and replaced once a month.
CHEMICAL ACTION
This filtering action works on the chemical substances in drinking water (e.g. chlorine, phosphates and nitrates), pigments that
reduce its clarity, potentially toxic organic compounds, drug residues and smells etc. With the NEWA Mirabello filter, this action
is carried out by plant-derived active carbon in the NEWA Mechanichem filter cartridge. This carbon has a very porous structure
and a wide surface area that allows a highly physical and chemical absorbent capacity. In this way, any harmful substance
inseparably sticks to the carbon that saturates it: this is why the Newa More Mechanichem filter cartridge needs to be replaced
regularly, about once a month.

BIOLOGICAL ACTION
This essential filtering action is carried out by nitrifying bacteria that colonize the biological base and the interchangeable
BioFoam filter cartridge. Biochemical transformations purify the water, removing organic substances deriving from the fish
faeces, food debris, decaying leaves and plant fragments. These weaken the aquatic fauna, making it particularly sensitive to
stress and diseases. In order of toxicity, these are (Fig. 11):
1. Ammonia (NH3), a very toxic substance that, with the presence of the correct pH, is soon transformed into ammonium ion (NH4
+), which is less toxic but chemically unstable.
2. Nitrites (NO2), the result of the transformation of NH3 and NH4 + by certain bacteria in the filter. It is a toxic compound even when
it is a low dosage.
3. Nitrates (NO3), substances derived from the transformation of nitrites by other bacteria. Within certain limits, nitrates are not very
toxic and well-tolerated by fish.
A newly set up aquarium requires special attention, since the filters do not yet have a sufficient quantity of bacteria for efficient
biological filtering. It is therefore advisable to wait at least 8-10 days after switching on the aquarium before introducing fish
and, at least during the first month of operation, feeding the fish sparingly, since food also contributes to increasing the quantity
of dissolved organic substances.
V.d ACTIVATION OF FILTERING CARTRIDGES
Biofoam:
Slightly rinse the sponge with warm water and install it back.
Mechanichem:
Do NOT rinse the filter cartridge containing the activated pre-conditioned carbon.
V.e PUMP-FILTER CUSTOMIZATION
The pump / filter has its own housing to place the filtered materials. Please perform the following steps to connect the associated
products (MIR 60/70: Ceramic cones) or to replace other materials:
Remove the pump along with its case for additional filtering by controlling the first rotation of the water drain reflector to the
internal part (Fig. 12). Separate the pump from the housing and remove the grid cover (Fig. 13). Open the section containing
ceramic cones and pour it into the housing (MIR60/70). The housing may be filled with filtering materials such as:
1) Ion exchange resin used to reduce water hardness (ideal for salt-rich water).
2) Peat filtration used to create the amber water. It is ideal for tropical fish from the rainforests.
3) Activated carbon to enhance the chemical filtration.
4) Special resin to strengthen the process of removing dissolved residual products.
5) Synthetic sponges or ceramic cones to enhance biological filtration.
V.f PUMPING CAPACITY REGULATION
Typically, the pump capacity is adjusted to the maximum power. It is necessary to adjust the specific mechanism to verify or
change the performance (Fig. 14).
V.g AERATION SYSTEM
If desired, it is possible to initiate the ventilation system built into the pump to improve oxygenation and gas exchange. To do
