INSTRUCTIONS
Choose the place where you will install your Junior CO
2
Kit (preferably beside the aquarium) or if
necessary below the aquarium.
a. A two-sided sticker is at the bottom of the bottle holder. This sticker is used to ensure the position
and stability of the system CO
2
. Remove the paper of the sticker
(fig. 1)
and place the bottle holder
in a place of your choice. Caution: once the sticker placed, you will not be able to move the bottle
holder any more. For reasons of safety and to ensure an optimal adjustment, the CO
2
cartridge/
bottle must always be placed in the bottle holder on a flat and horizontal surface.
b. Take the pressure regulator and close it by hand, turning it in the clockwise direction
(fig. 2)
.
c. Take the CO
2
cartridge/bottle. Check if there is no dust or dirt in the threading of the pressure
regulator or on the thread of the cartridge/bottle. Clean if needed, by blowing strongly. Now connect
it to the pressure regulator while turning the bottle clockwise until you feel a light resistance. At this
time, the bottle is against the bottle pressure part. Keep on turning until the cartridge/bottle is tightly
fixed
(fig. 3)
.
ASSEMBLY
Take the pressure regulator, remove the bolt from the pressure regulator
(fig. 4)
and slide the bolt
over the special CO
2
tubing
(fig. 5)
. Now place the special CO
2
tubing with the bolt back over the
pressure regulator
(fig. 6)
, and tighten it firmly by hand
(fig. 7)
. The assembly of the pressure
regulator is now complete.
Check-Valve :
The check-valve is placed on the side of the aquarium, with the arrow pointed
upward. To easily slide the special CO
2
tubing over the check-valve and afterwards on the bubble
counter, we recommend making the tubing wet with lukewarm water. Now connect the check-valve
at the bottom with the special CO
2
tubing
(fig. 8)
. Connect a piece of CO
2
tubing (2 - 3 cm length )
over the top of the check-valve. Now attach the filled bubble counter.
Bubble Counter :
Inside the bubble counter, you’ll see an upright tube
(fig. 9a)
. The upright tube
position goes into a glass filled with water. Let it fill for ¾ with water
(fig 9b)
. Take the bubble
counter out of the glass, and keep your finger on the opening at the top, so the water doesn’t run
out
(fig. 10)
.
Now connect the bubble counter on the check-valve
(fig. 11)
. Attach the now connected bubble
counter/check-valve with suction cups to the aquarium on a visible place
(fig. 12)
. Caution: the
Check-Valve and the Bubble-Counter must thus be handled with the greatest prudence. While
assembling, never use excessive force, this could cause damage.
Ceramic diffusor :
Determine and cut the length of the special CO
2
tubing you need to install
the ceramic diffuser at the bottom and in the front of your aquarium. Now connect it to the bubble
counter
(fig. 13)
. The ceramic diffuser is assembled with a small elbow, supplied with the Junior
Kit. This permits a horizontal placement, thus optimizing the distribution of CO
2
(fig 14 & 15)
. A
suction cup is also supplied, to easily attach the diffuser to the aquarium. The placement in the
aquarium in the front and just above the layer of gravel enables you to check on the distribution of
CO
2
(fig. 16)
. Caution : make sure the special CO
2
tube is never folded.
INSTALLATION :
As seen earlier, you will find the button of adjustment on the top of the regulator.
While slightly turning the button anti-clockwise, you open the regulator and CO
2
will be released.
Wait a few minutes until small CO
2
bubbles gently leave the ceramic diffuser and go up slowly
towards the surface. It is important that CO
2
is released in tiny bubbles. Remaining as long as
possible in contact with water, thus helping an optimal dissolving process, in which plants can
assimilate a maximum of dissolved CO
2
. The finer the bubbles, the easier they will be dissolved.
The quantity of CO
2
used will be optimised and the best assimilation will be achieved for all water
plants. It is important to follow the above instructions. When, after 5 minutes, no CO
2
comes out
the ceramic diffuser, turn the button some more anti-clockwise. Do not forget to stop the CO
2
diffusion when lighting is out. Indeed, light is the source of the aquarium plants and they start their
photosynthesis process. Now a distribution of CO
2
is required. Thus, plants do not assimilate CO
2
when light is off. Keep this in mind every time you turn the lighting on or off.
Important :
After closing the pressure regulator, the ceramic diffusor still emits CO
2
for a short
while. This is absolutely normal, the remaining CO
2
in the tubing is still under pressure. In the
morning the reverse happens : after opening the pressure regulator, it can take a while before CO
2
is released. This procedure is ideal for the photosynthesis process, because the plants are not
capable of assimilating CO
2
immediately after the light is switched on. If the ceramic diffusor stops
emitting small bubbles, then this indicates the cartridge/bottle is empty. You can control this by
checking the pressure gauge.
