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 ranging from 2 - 4 mm, plants can grow excellently. And because its grains are rounded, the natural gravel is also suitable for breeding bottom-dwelling fish like catfish.

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