|Within the wheel, is a
protected surface, which enables colonies of bacteria to naturally
follow their life cycle, maturing and dying, in turn fuelling the latter
stages of the nitrification conversion process.
It also assists in the breakdown of any small particles passing
through from the mechanical stage. Therefore, the Kaldnes media
maintains both a young bio film and a maturing bio film providing a more
consistent filter performance, whilst improving water quality,
encouraging healthier Koi and aiding in reducing green water and blanket
Due to chaotic movement of the Kaldnes K1 media, the process is
self-cleaning and requires no maintenance. This allows the filter to
reach optimum effectiveness without the disturbance of periodic
maintenance, avoiding unnecessary loss of bacteria within the filter
preventing high levels of ammonia and nitrite within the water.
