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