Clean
water is continuously
fed into the tank.
Surface Skimmer. The water from
the tank spills over into the surface
skimmer, which feeds the water through a
mechanical filter. This filter removes
unwanted particles and debris. The water
is taken from the top of the tank to
provide oxygenated water to the bio
filter area.
Biofilter. This area is
made up of many high surface area
'bioballs', and they are kept wet by the
continous flow of water over them from
the surface skimmer. The bioballs provide
ideal growing conditions for benefical
bacteria, which clean the water of
biological impurities.
This
area provides an overflow capacity, so
that if there is a power failure, the
excess water from the tank flows into
this area.
The pump. This unit
drives the water through the system.
The chiller. This unit,
which is optional, depending on the
specimens kept, will cool the water to an
ideal temperature.
The
cleaned
and conditioned water is then fed back
to the tank.
