Many aquarists indeed discover that their aquarium works just as well without its filter.
In the early 2000s, the success of the poubellarium represented a subtle yet profound break in aquarium knowledge.
The idea was to offer them a bit of real wild life after a winter in an aquarium, less stress and a feeling of captivity.
No heating and therefore irregular temperatures, no ventilation, no filter... nothing met the standards of aquaristics.
Yet, against all odds, it was observed that fish often developed much better and were healthier in these rather... surprising conditions.
The first reactions, reluctantly, were to concede that it could work provided there are very few fish.
But, once again, the experience showed the opposite.
Especially since some had already taken the plunge and also removed the filter from their aquarium... without any unfortunate consequences.
Aquarium filters are attributed two functions, a mechanical function and a biological function, in the absence of a filter, the first function is no longer guaranteed, but the biological function is perfectly ensured without a filter.
An aquarium rich enough in microbial diversity is a filter in itself, these bacteria ensure all biological cycles, including the famous nitrogen cycle.
This cycle generally consists of transforming organic matter into nitrites, then into nitrates, and this can be done with or without a filter, it works just as well.
To do without a filter, it is therefore enough to allow a maximum microbial diversity to settle, this is the role of the Zollabox startup which provides an aquarium or a poubellarium, or even a pond, with the millions of microbial species included in its three doses.
