Congratulations on purchasing this high-quality CO
2
diffuser from Dennerle. If used properly and treated with due care, this diffuser will provide your aquarium
with a reliable and consistent supply of CO
2
– the most important fertilizer for aquarium plants.
Dennerle wishes you lasting enjoyment from your aquarium!

How the CO
2
Cyclo Turbo works
The CO
2
supplied by the CO
2
fertilizer system issues from the opening of the CO
2
tube. From here, the bubbles rise to the surface and collect beneath the individual
steps of the Turbo attachment.
The water coming from the filter whirls in a downward direction past the ‚trapped‘
CO
2
bubbles. Thanks to this counter-current principle, which is frequently found in
nature too, the CO
2
is able dissolve extremely quickly and effectively.
The CO
2
-enriched water then flows into the aquarium at the bottom end of the whirl
chamber
The amount of CO
2
supplied can be calculated on the basis of the number of bub-
bles per minute.
The atomizer jet and waste-gas vent
While the CO
2
dissolves into the water, other gases that occur naturally in aquarium
water penetrate the CO
2
bubbles. These so-called waste gases explain why the bub-
bles become smaller the further up the tank they rise but never dissolve complete-
ly. When the bubbles reach the head of the whirl chamber they already consist
almost entirely of waste gases and contain barely any CO
2
at all. Here they are
drawn into the atomizer jet and split into thousands of tiny bubbles. This allows the
remaining CO
2
to dissolve before the waste gases are drawn off via the specially desi-
gned waste-gas vent.
Cyclo Turbo and aquarium size
The device is highly effective, despite its compact design. The Cyclo Turbo can
provide aquariums
up to 750 litres
with CO
2
at normal levels.
The capacity of the device can be considerably expanded to fit any aquarium. A Cyclo
extension (Order No.: 1588) and a Cyclo Turbo insert (Order No: 1580) are
available for this purpose. Each extension module increases the range by a
further 750 litres
.
The Cyclo Turbo is compatible with all commercially available CO
2
supply systems.

How to install the
Cyclo Turbo correctly
1. Rinse the Cyclo Turbo with warm tap water.
Do not use detergent!
2. Insert the control tap into the Cyclo head.
Attach the CO
2
supply hose to the hose
connector.
TIP: Dipping the end of the hose into hot
water briefly beforehand makes it easier to
slide it over the hose connector.
3. Select a suitable spot in the aquarium to
affix the unit. The spot should not be too
bright, to prevent possible algae growth.
Using the suction cups, attach the Cyclo ver-
tically in the aquarium at least 5 cm below
the surface of the water.
4. Attach the control tap to the water outlet of
the motor filter or a separate pump using a
suitable hose. The Cyclo head can be turned
for this purpose.All standard hoses sized
9/12 mm, 12/16 mm and 16/22 mm
fit.
5. Set the required amount of CO
2
at the pres-
sure reducer. For this purpose, please also
consult the instructions for use provided with
the other components of your CO
2
fertilizati-
on system
Setting the control tap
With the aid of the control tap it is possible to direct part of the water coming
from the filter into the Cyclo cylinder for the purpose of dissolving CO
2
. The rest of
the water runs through the outlet nozzle
straight back into the aquarium.
• Position A: No water is fed into the Cyclo.
• Position B: 50 % of the water is fed into the
Cyclo and 50 % into the aquarium.
• Position C: All the water is channeled into the
Cyclo cylinder.

Cyclo Turbo
Powerful, compact CO

diffuser for aquariums.. With waste-gas vent.
- Instructions for use: please read carefully and keep in a safe place. -
The control tap should be set in such a way as to enable as much water as possi-
ble to flow through the Cyclo cylinder without forcing the CO
2
bubbles down, instead
allowing them to rise slowly.
