At the third or fourth week, the concentration of nitrites reaches a maximum, which also, despite the decrease in ammonium concentration, it is dangerous to aquarium inhabitants. In turn, the bacteria of another species, consuming nitrites, gradually reduce their concentration, and biofilter begins to work normally.
