Sera white gravel is resistant to carbon dioxide and neutral towards water, meaning it has no effect on water parameters and does not change the color of the water. Thanks to the grain size of 1 - 3 mm, plants can grow excellently. And due to its rounded grains, the natural gravel is also suitable for breeding bottom-dwelling fish such as catfish.

Sera white gravel is classified according to the DIN 38415-6 / EN ISO 15088 standard by an independent institute, and it has been proven to be free from contaminants. Therefore, it is also suitable for breeding and caring for sensitive animals.
