FLUVAL ADVANCED FILTRATION
There are three basic types of filtration. Mechanical filter
media removes waste particles and solid debris through
mechanical strainers. Biological filter media breaks down
and eliminate organic toxins—ammonia and nitrite—
through bacterial action. Chemical filter media actively
changes water characteristics through deliberately
managed chemical reactions.
Fluval offers a wide variety of filter media materials. Some
perform more than one job. This is the true power of the
Fluval system—the broad range of media available for use
in its baskets. These extensive choices give you maximum
flexibility in designing the aquatic environment just right
for your aquarium.
The Fluval Stack of Media Baskets
The stack of large capacity media
baskets in the Fluval FX6 filter
enables you to employ all three
types of filtration in whatever
configuration or sequence
determine is best to meet the needs
of your aquarium environment.
Filtration always begins with a
mechanical stage of waste particle
removal as water is drawn through
the foam that lines the perimeter
of each basket. Subsequently, the
flow proceeds through the central
area of the three baskets from top
to bottom, where it is filtered by
additional mechanical, biological
and chemical stages: the water is
pumped down through the media in
the three baskets. Because you can
use the media of your choosing at
each level, you will be able to design
a system that provides additional mechanical, biological
and chemical filtration if you wish. For detailed information,
as well as general guidelines for media selection please

GENERAL GUIDELINE
Location can determine function: For example, BIOMAX
can act primarily as a screen for debris or act more as an
environment for growth of beneficial bacteria, depending
on where it is placed in the filtration sequence. Proper
preparation is key: some materials, such as Ammonia
Remover, require thorough rinsing so that their finest
particles do not clog other modules or discharge into the
aquarium. For best results and the protection of your fish,
always read and follow the preparation instructions for the
media you are using. Use mechanical filter media in the
first stage of filtration: this helps ensure that the water
will be as free of debris as possible when it flows through
you
biological and/or chemical filters, which require clear water
for maximum effectiveness.
To achieve maximum effectiveness, Fluval FX6 offers three
types of mechanical filtration: the external white foam traps
the larger particles, the black foam traps smaller particles
and the carbon foam provides an additional barrier
to protect the pump. Protect chemical media from
debris: chemical filtering media modifies the chemical
characteristics of the water by absorbing toxic compounds
(eg, medicines, odours and organic contaminants). Therefore
it is necessary to prevent the chemical filter media from
clogging by macro and micro-particulate. Placing chemical
filter media at the last stage of filtration will allow it to
work best.
1
Top Media Basket
Media that continues the mechanical
capture of small particles should be
placed in the top basket, to purify water
and/or remove particles before they
can clog delicate pores of biological
or chemical substrates. The Bio-Foam
is ideal to remove small dirt particles
that are not retained by the Mechanical
Foam. In addition, this foam provides a
large surface to accommodate bacteria
colonies, providing a good environment
for proliferation of beneficial bacteria and
increasing the biological action of Fluval
BIOMAX.
2
Middle Media Basket
The middle basket is a good place to
establish the biological detoxification
process. A lot of media types provide both
mechanical filtration and biological treatment, creating an
excellent environment for beneficial bacteria to proliferate.
With the primary mechanical purification of the water
stream occurring in the Mechanical Foam and the Bio-
Foam, it is typical to load biological media such as BIOMAX
into the mid level basket.
3
Bottom Media Basket
This basket receives the clearest water, making it the
ideal place for dedicated chemical media. Placed here,
the supplied Carbon Foam or the additional Granules, for
example, efficiently remove discolorations, medications
and solubilized wastes that a mechanical screen cannot.
The bags included in the package are ideal for storing any
type of granular chemical filtering media. Please refer to
the following section for further information to choose the
best chemical media for your aquarium.
