ADA KUMU Hazel Gravel from the KUMU Layout series impresses with its unmistakable reddish-brown and cream-coloured marbling, which appears almost amber-coloured when wet. This substrate is ideal for aquariums and paludariums and gives any water basin a natural and aesthetically pleasing look.
Hazel Gravel is also available in a finer version, KUMU Hazel Gravel S. The combination of both variants creates a natural depth effect in the layout, which makes the overall look even more realistic and attractive.

With a grain size of 20 - 30 mm and a packaging quantity of 250 ml, KUMU Hazel Gravel offers ideal conditions for use in a wide variety of aquascaping and terrascaping applications. The substrate has a strong influence on the total hardness (GH) of the water and a medium influence on the pH value. However, these influences can be effectively counteracted by regular water changes, ensuring stable water quality.

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.
