Rinse the glass under running water.

The FAN 2 and FAN 3 models have a removable plastic prefilter attached to the glass. It also needs to be flushed from obvious contamination.
The sponge removed from the perforated rod is washed in the water drained from the aquarium approximately once a week, the frequency depends on the population density of the aquarium.
The large-pore foam rubber from which the sponge is made effectively delays the pollution formed during the life of the fish.

It is necessary to understand that this sponge performs the function of not only a mechanical, but also a biological filter. On the surface of AQUAEL bisphenol sponges ideal conditions are created for the life of beneficial nitrifying bacteria oxidizing ammonia and nitrites. Nitrifying bacteria are very sensitive to the presence of chemicals in the water. That is why the sponge should be washed in water drained from the aquarium.

For the normal life of bacteria requires a large amount of oxygen. Therefore, a break in the filter operation lasting more than 3-4 hours, as a rule, leads to its complete sterilization (death of beneficial bacteria), as a result of which it will have to be re-washed and “started”.
It must be remembered that over time sponges wear out without losing appearance. Therefore, at least once every six months, the filter material should be replaced with a new one.

Timely replacement of sponges has a positive effect on filtration and aeration efficiency in the aquarium.

Sponge should not be washed with water from the tap, as it is the habitat of nitrifying bacteria responsible for biological filtration. Tap water kills all good bacteria.

Filters FAN plus series are powered by a hermetic synchronous motor that does not require complicated maintenance. However, approximately twice a month it is necessary to remove the cup and the lid of the rotor chamber, remove the rotor and carefully clean it and clean the rotor chamber.

After that you should collect filter in reverse order.
