ADA KUMU River Gravel S from the KUMU Layout series is a special, flat gravel with rounded corners that is reminiscent of Japanese river beds and creates a refreshing atmosphere. This gravel is available in a grain size of 5 - 10 mm. The unique shape of the gravel helps to recreate natural river landscapes and creates an aesthetically pleasing look.
In addition to the fine KUMU River Gravel S variant, there is also a coarser version of this River Gravel. The combination of both variants enables an even more natural aquarium design that is reminiscent of real river landscapes.

KUMU River Gravel S has a high influence on the total hardness (GH) and the pH value of the water, which should be taken into account. This influence can be controlled by regular water changes to ensure stable water values.

The KUMU series is not only suitable for use in small glass showcases as paludarium decoration material, but also as a versatile design material for optimising compositions and refining scenic arrangements in aquascapes.
