Sera Gravel Ocher (Ø 0 – 2 mm) for all freshwater and marine aquariums
sera Gravel Ocher 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 0 – 2 mm, plants can grow on excellently. Due to being round grained, the natural gravel is also suitable for keeping bottom oriented fish such as catfish.
sera Gravel Ocher 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.
