The graph shows that phosphate concentration in
the water column is reduced and maintained at a
safe value for more than two weeks.
Fluval G3/G6
Nitrate Cartridges
The Fluval G3 Nitrate
cartridge is for use with
the Fluval G3 Advanced
Filter System, and will
remove up to 13000
mg of nitrate ion in
freshwater aquariums.
The Fluval G6 Nitrate
cartridge is for use with the Fluval G6 Advanced
Filter System, and will remove up to 24000 mg of
nitrate ion in freshwater aquariums
Nitrate concentration should not exceed 20 mg/L in
freshwater aquariums; however planted aquariums
require approximately 5mg/L of nitrate as a source
of essential nitrogen for healthy plant growth.
In a 300 L / 600L freshwater aquarium with a 30
mg/L nitrate concentration, the use of G3 / G6
Nitrate cartridge will quickly remove all excess of
nitrate in a couple of days. If left in the filter, it will
then maintain a low nitrate 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). Nitrate is irreversibly trapped/bound, and will
not leach back into the water. The continuous use
of the G Nitrate cartridge in aquariums with persis-
tent nitrate problems is an effective solution against
nitrate accumulation. If used as a quick solution to
reduce elevated nitrate concentrations, the cartridge
can be removed once levels have normalized, and
then stored until required.
In the following example, a 600L freshwater aquar-
ium was treated with the G6 Nitrate Cartridge. The
concentration of nitrate was reduced from over 20
mg/L to less than 5 mg/L and remained around
this value for over 30 days. Then the concentration
started to slowly rise and was back to 20 mg/L
in about six months. During this period no water
change was performed.
Fluval G3/G6
Tri-Ex Cartridges
Fluval G3 / G6 Tri-Ex
cartridge is for use with
the Fluval G series of
Advanced Filter Systems,
and combines the bind-
ing power of Fluval G
phosphate, nitrate and
carbon for an all in one
pollution management
solution for fresh water aquariums. With the contin-
ued use of Tri-Ex, nitrates, phosphates and organic
pollutants remain under control. The G3 cartridge
binds over 5000 mg (or more than 15 mg/L in a
300 L aquarium) of nitrate and over 600 mg (or
more than 2 mg/L in a 300 L aquarium) of phos-
phate. The G6 cartridge binds over 9000 mg (or
more than 15 mg/L in a 600 L aquarium) of nitrate
and over 1100 mg (or more than 2 mg/L in a 600
L aquarium) of phosphate. The specialized mesh size
of the carbon component maximizes the surface to
volume ratio for optimized performance.
