FLUVAL G FILTER FILTRATION MEDIA
Mechanical (Pre-Filter) Cartridges
A healthier aquarium environment is guaranteed
through more frequent and easier cartridge
cleaning and/or replacement. Due to the special
nature of the mechanical pre-filter cartridge, solid
waste is removed from the aquarium before it can
be solubilized, thus dramatically reducing ammonia
and nitrite problems, nitrate and other waste build
up. This G filter cartridge system concept is based
on preventative maintenance. Remove the waste
BEFORE it pollutes the aquarium.
Fluval G3 / G6
Mechanical Pre-Filter
Cartridge
The Fluval G3 / G6
Pre-filters are daily use
cartridges for the
Fluval G3 / G6
Advanced Filter Systems,
and will trap suspended
debris for effective mechanical filtration in fresh or
marine applications. Designed as a “no by-pass”
system, debris remains caught between each pleat
until it is removed and rinsed. For extended use, it is
recommended that the cartridge is cleaned at least
every 2-3 weeks.
Fluval G3/G6 Fine
(75µm) Mechanical
Pre-Filter Cartridge
The Fluval G3 / G6 Fine
Pre-Filter Cartridges are
designed for daily use
with marine aquariums,
where suspended debris
is minimal. They can also
be used as polishing
cartridges for standard or freshwater aquariums.
The fine mesh will trap debris 75μm or larger for
unparalleled mechanical filtering results. Designed as
a “no by-pass” system, debris remains caught
between each pleat until it is removed and rinsed.
However, solid wastes can beak down into soluble
wastes and regular cartridge rinsing is
recommended.

Phosphate Cartridges
The Fluval G3 / G6
Phosphate cartridges
are for use with the
Fluval G3 / G6 Advanced
Filter Systems. The G3
cartridge will rapidly
remove up to 2200 mg
of phosphate ions, and
the G6 cartridge will
remove up to 3900 mg of phosphate ions from
marine or freshwater aquaria.
Phosphate is one of the main causes of uncontrolled
algae growth in aquariums, and its concentration
should not exceed 0.5 mg/L in freshwater
aquariums and 0.05 mg/L in marine aquariums.
In freshwater aquariums with an excess
concentration of 1-2 mg/L phosphate
concentration, the use of the Fluval G phosphate
cartridges will remove all the excess of phosphate
within 1 or 2 days. If left in the filter, it will sustain
a low phosphate level for a period of time that is
strictly dependent on the type of aquarium it is.
(Quantity and type of fish, type of fish food and so on)
Phosphate is irreversibly trapped/bound, and will not
leach back into aquarium water. The continuous use
of the Phosphate cartridge in aquariums with
persistent phosphate problems is an effective
solution against phosphate build up. If used as a
quick solution to reduce elevated phosphate
concentration, the cartridge can be removed once
levels have normalized, and then stored until
required.
It is suggested to regularly monitor the phosphate
concentration in the aquarium water; when the
concentration value starts to rise, it is time to use
or replace the cartridge to ensure the continuous
protection against phosphate accumulation.
In the following example, a 600 L freshwater
aquarium with high phosphate concentrations
(2.2 mg/L) has been treated with the Fluval G6
phosphate cartridge.
