Water level in the container too
low, foam filters are not com-
pletely immersed in water. The water level is initially lower when new foam fil-
ters are fitted as they have not yet been colonised
by bacteria. – It takes several weeks for the bacteria to become
established and the foam filters to become fully ef-
fective.
– Use OASE filter starter Biokick to speed up the col-
onisation of bacteria.
