Introduction

Thank you for choosing a JUWEL Aquarium product.
Our products represent over 40 years experience in the manufacturing of aquariums

and their acessories applying most modern production techniques bringing together
the JUWEL Aquarium system, which is both easy to use and simple to maintain.

Important:

Please read this instruction manual carefully and completely to make sure you
have received all components before setting up the aquarium.

Please observe the safety instructions and maintenance guidelines given in this
manual.

This instruction manual has been carefully prepared to provide you with accurate
and complete information. All efforts have been made to ensure that the
information given is correct. However, we cannot accept responsibility for
printing or other errors. Technical details are always approximate and are not
warranted characteristics and may be subject to change without notice.

Always unplug all immersed electrical equipment from mains before placing your
hands into the water.

Important:

The use of additional air stones or air lines is not necessary with the JUWEL
Aquariums. If an air stone is used, this should always be placed in the middle of
the aquarium. Capillary leaks resulting from the use of these items will not be
accepted as a fault with the aquarium.

Do not transport or move your aquarium while still containing water or sand.
Always take care not to damage the seals while maintaining your aquarium.
Do not use toxic substances to clean your aquarium.

Safety instructions:

This appliance is not intended for use by persons (including children) with
reduced physical, sensory or mental capabilities, or lack of experience and
knowledge, unless they have been given supervision or instruction concerning
use of the appliance by a person responsible for their safety. Children should be
supervised to ensure that they do not play with the appliance.

Operation with the RC circuit breaker only, max. 30mA.

The power plugs of the electrical devices must not become moist. Connect the
power plugs to the power supply at such a height that the connection cable
forms a loop which would enable the water to drip down.

Setting up the Aquarium

We have produced your JUWEL Aquarium with the utmost care using most advanced
production techniques. Extra strong packaging has been used to prevent damage to
the aquarium. Please note however, that your aquarium has been transported and
handled several times prior to reaching its final destination. We recommend
therefore, that you test the aquarium for leaks in a suitable area (e.g. garage), by
filling it with water and checking it very carefully.

Having made your checks, you should select the most suitable and desirable position
for your aquarium. The position selected should have an even and level surface and
should be able to support the weight of the filled aquarium. In order to prevent
excessive algae growth, we recommend that you select a position that is not exposed
to direct daylight.

We strongly recommend that the appropriate JUWEL Aquarium cabinet is used. They
have a water-repellent surface and they have been made to match the dimensions and
to bear the weight of the filled aquarium. The cabinet must be positioned on a level
surface. The JUWEL Aquarium is built with a special bottom frame for security. The
aquarium should be placed directly onto the cabinet. DO NOT place any additional
support, e.g. polystyrene, under the aquarium since this is not necessary with our
aquariums.

Setting up your JUWEL Aquarium

In order to set up your aquarium and to prepare it for its intended use, please follow
the following guidelines.

1. Make up the appropriate JUWEL Aquarium cabinet.

2. Place the aquarium in its chosen location.

3. Ensure that the filter system is set up according to the instructions as described in
this manual.

4. Place your substrate in the bottom of the aquarium and plant as desired.

5. Fill the aquarium with room temperature water slowly through the filter to the red
fill line indicated inside the aquarium - Important - do not over fill!

6. Connect the powerhead and heater and complete by placing the light unit and flaps
on the top of the aquarium.

7. For tropical set-ups, allow the aquarium to reach the desired temperature prior to
the addition of livestock.

You can add a few hardy fish after only a few days since you will need some livestock
to start the filter maturation process. The filter can take between 6 and 8 weeks to
fully mature. Should you choose to add further livestock during this period, then this
should be a gradual process.

The JUWEL filter system Bioflow

The JUWEL filter system Bioflow is a highly effective biological filter system with two
stages that includes components complementing each other in an ideal manner.
Installing the filter in the aquarium makes hose connections unnecessary and prevents

leaks. The pump output is not negatively affected by hose couplings, intake tubes etc.
The capacity of the pump is designed in such a manner that an ideal level of biological
filtering is ensured by a sufficient level of percolation through the filter material.

In that context, the large filter volume ensures excellent mechanical filtering and
facilitates long cleaning intervals.

The JUWEL filter system Bioflow enables you to achieve a look in the aquarium which
is characterized by almost no discernable water movement. Accordingly, the fish is
exposed to less currents, and you achieve a semi-natural peaceful environment for fish
and plants. The construction of the filter system enables you to quickly access the
individual heater, pump, and filter media components. This way, the filter system may
comfortably be operated during cleaning and while performing maintenance work.

Bioflow Super

Filter Wool (white pad)

The white filter wool acts as a mechanical pre-filter, removing large particles of dirt
and excess food which in turn ensures that the other sponges do not get clogged.

Active Carbon Sponge (black)

The black activated carbon sponge sits on top of the blue coarse filter sponges, and
removes chemical impurities from the water which cannot be removed biologically.

Nitrate Removal Sponge (green)

The Sponge contains micro-organisms, which will, once developed, reside inside the
sponges and in the water. These micro-organisms feed of nitrates and will reduce them
significantly. The JUWEL Filtration system provides the optimum housing for these
micro-organisms.

Filter Sponge Coarse (blue)

The coarse blue filter sponges allow bacteria cultures to develop quickly, cleaning the
water which is now free from chemical impurities.

Filter Sponge Fine (blue)

The fine blue sponges and the bacteria cultures living in them, clean the water of even
the smallest impurities.

Cirax

The highly porous filter material utilizes its extremely large surface for effective
biological cleaning and ensures the highest water quality.
