sera Gravel Black 2-3 mm 3.000 ml

Black colored gravel (Ø 2 - 3 mm) for all freshwater and marine aquariums

sera Gravel Black is CO₂ proof and neutral towards water, i.e. it has no influence on water parameters and does not tint the water. Due to a grain size of 2 - 3 mm, plants can grow on excellently. Due to being round grained, the colored gravel is also suitable for keeping bottom oriented fish such as catfish.

sera Gravel Black is evaluated according to DIN 38415-6 / EN ISO 15088 by an independent institute, and is proven to be pollutant free. It is therefore also suited for keeping and breeding sensitive animals.
