Black colored gravel (Ø 2 - 3 mm) for all freshwater and saltwater aquariums.
sera Gravel Black is CO2-resistant and water-neutral, i.e. it has no influence on the water parameters and does not colour the water. Thanks to the grain size of 2 to 3 mm, plants can grow perfectly. Thanks to its rounded grain size, the coloured gravel is also suitable for keeping bottom fish such as catfish.
sera Gravel Black has been tested by an independent institute according to DIN 38415-6 / EN ISO 15088 and proven to contain no harmful substances, so that it is also suitable for the maintenance and breeding of sensitive animals.
