Sera beige gravel is resistant to carbon dioxide and neutral towards water, meaning it has no effect on water parameters and does not color the water. Thanks to the grain size of 2 - 4 mm, plants can grow excellently. And because it has rounded grains, the natural gravel is also suitable for breeding bottom-dwelling fish like catfish.

Sera beige gravel has been evaluated according to DIN 38415-6 / EN ISO 15088 standards by an independent institute, and it has been proven to be free of contaminants. Therefore, it is also suitable for breeding and caring for sensitive animals.
