The aquarium is an artificial habitat for tropical fish and plants. Even the largest aquarium is just a small water puddle in comparison with the natural biotope. Without appropriate regulation the chemical and physical conditions in it will very quickly go from one extreme to another Thus fish and plant life in the aquarium is not possible without corresponding control by the aquarium operator.

Building upon the decades of experience of Horst E. Kipper and Kaspar Horst, Dupla today offers a wide range of aquarium systems that provide optimum conditions for fish and plants, partially even better than in nature.

The basis was formed by countless biotope investigations in the native countries of aquarium fish and plants, and the findings gained have been transformed into practical aquarium terms by means of numerous tests and extensive development work. Horst E. Kipper and Kaspar Horst have documented this work in their books, publications and magazine articles.

DUPLA CO2-Set Omega

• Natural source of carbon dioxide
• Optimum efficiency
• Capacity for approx. 1 month
• Suitable for all aquariums up to 150 litres
• Refills available

CO2 supply provided by the 1 litre reaction chamber which is situated outside of the aquarium. CO2 distribution within the tank is carried out by the power head which is provided in the kit. CO2 production from the natural ingredients last approx 30 days

(Please note : Instructions state that bracket and fixing screws are included in the package. These are no longer included as the new bottle material  is much stronger under pressure and are therefore not required. New instruction sheets are being introduced)

This set provides everything the aquarist needs for a good and quick start with CO2 fertilisation in his aquarium. The Dupla CO2 Set Delta includes the pressure reducer fitting Delta complete with 100 bar pressure gauge. The fitting Delta reduces the cylinder pressure from approx. 60 bar, to a constant working pressure of 1 bar. The CO2 Set Delta also includes a CO2 atomiser (with integrated non-return valve) which evenly distributes the CO2 gas within the water, the permanent CO2 visual test, and all necessary tubing etc.

Suitable for tanks up to 400 litres

CO² Cylinder is NOT included

This small CO2 test indicator fits inside the tank with part of it under the water. The reagent within the test reacts with the water to give a colour change within the tester which indicates the level of carbon dioxide within the tank water

Permanent test should be refilled at least once a month

Supplied with 10ml of Reagent, and colour indicator

If aquarium plants are to grow and thrive, they need, besides water and light, a certain selection of nutrients. Since the aquarium is an artificial biotope, these nutrients are, however, not available indefinitely. The nutrients must be introduced into the biosystem from the outside.

Dupla Root is the ideal nutrient deposit for all aquarium plants and should be added to the aquarium gravel

• It is rich in iron available to the plants
• High trace element content
• Prevents deficiency symptoms
• pH neutral
• Dupla Root activation bacteria sachets included

180ml ( 200gm) is sufficient for tanks up to 180 litres

Follow-Up or additional basic Root Fertiliser

• Promotes growth and appearance
• Rich in available iron
• Prevents deficiency symptoms
• Light and oxygen stable
• pH Neutral
• Phosphate free

1 tablet sufficient for basic fertilisation of bottom bed of 10 litre tanks and should be added to the gravel bed

Pack treats 120 litres

For best results : Dupla Root K should be used in conjunction with Dupla Plant and Dupla Plant 24

DuplaRin is a modern food conception for aquarium fish. It was developed over many years through intensive research and testing in close co-operation with leading scientists. DuplaRin is a granulate available in different sizes; the right size and type for every fish and mouth size. Due to the especially gentle manufacturing process all carefully selected vitamins, proteins and trace elements are fully maintained. The most important advantages of DuplaRin:

1. DuplaRin is easily digestible. It consists of valuable raw materials which through their balanced composition enhance the health of aquarium fish.
2. DuplaRin is adapted to the fish’ mouth sizes and also their eating habits. Fish are usually consumers of morsels, and because mouth sizes vary, DuplaRin is available in different granulate sizes suitable for every individual requirement.
3. DuplaRin is a 3-stage food product because it floats, swims and sinks. Fish existing in all three zones of the aquarium (top, middle zone, bottom area) are supplied with an equally fresh and comprehensive nutrition.
4. DuplaRin is water stable. It slowly absorbs water, without losing its shape or breaking up. Valuable components are maintained and are not being diluted. The aquarium fish are thus always supplied with a high-value diet.
5. DuplaRin is easy to dose. An entirely new method of fish feeding was developed with a dosing device specifically designed for the DuplaRin granulate. This dosing device enables a targeted, precise and hygienic feeding of fish without wasting any food.(65ml size only)

A complete granulated food for freshwater and marine fish : with added Vitamins.

Aquarium Planting System

With a Dupla Creativ Module aquarium plants are set in dishes and only then inserted into the preformed substrate mat. Since most aquarium plants have been cultivated above water (emerged) in aquatic plant nurseries, the design and arrangement of the boxes - as well as the entire aquarium - can be done outside of the aquarium.

All systems include :

• Dupla Thermik-Set Omega Heating Cable
• Plastic planting boxes
• Foam Matrix for holding plant boxes
• Dupla Plant Fertiliser
• Dupla Root Basic Fertiliser Tablets
• Dupla Plant 24 fertiliser
• 1.5m of 12mm hose for water changes
• 20 litre plastic water change container (bucket)
• Full instruction booklet

Dupla Creativ 80 : 8 planting trays : 8 hole matrix : 700mm x 330mm approx.

Dupla Creative 100 : 10 planting trays : 10 hole matrix : 870mm x 330mm approx
