ULTRA-POROUS BIO-MINERAL FILTER
The aquarium is a closed system, which therefore requires a filtering system to eliminate toxic substances such as ammonia and nitrates, thereby guaranteeing the purity of the water and the well-being of its inhabitants. In order to do this, a family of bacteria (Nitrosomonas and Nitrobacter) are used. These bacteria, during the nitrogen cycle, transform the ammonia first in nitrites and then in nitrates, which are far less toxic. Equohas developed STILLA as an ultra-porous, bio-mineral support which the bacteria can inhabit and carry out their purification action while receiving the correct amount of water and oxygen.
INSTRUCTIONS FOR USE
Insert the contents in a wide net and rinse under running water to eliminate any dust or residue. Place them in the biological container of the filter. Protect STILLA from dirt by placing it after the mechanical filter. The content of a box of STILLA is sufficient to filter a normally populated aquarium of approximately 100 litres. With time, the impurities and the calcium present in the water tend to block the pores of the filter. Stilla has been developed to maintain a high level of filter efficiency, in fact, it should only be necessary to substitute half the product every six months.
