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.

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

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

Follow-Up or additional basic Root Fertiliser

The ideal nutrient combination for aquarium plants

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

Dupla Ground is a lime-free, water-neutral substrate.

It ideally supports plants and has a highly decorative effect.

Its grain size of 2-4 mm aids circulation in the aquarium bed, while its round form is ideally suited for ground dwellers such as catfish and loaches.

Should be washed with warm water prior to use
