The Aquael Natural Gravel is a natural substrate that is evenly distributed in the aquarium to provide support for plants and to collect nutrients for strong rooting. The natural gravel provides an attractive and natural appearance in the aquarium due to its mixed colors. The bottom material does not contain any artificial additives or coatings, which is why it behaves in a water-neutral way and does not release any polluting substances.

Aquael Natural Gravel is available in three different grain sizes:

• 1,4 – 2 mm,
• 3 – 5 mm
• 5 – 10 mm.

For shrimps and small fish, we recommend a grain size of 1,4 – 2 mm. Due to the rounded edges, there is no risk of injury with this substrate. In addition, the fine grain size is visually very appealing for nano aquariums, as these create an ideal size ratio for small aquascapes
