Sera

sera Gravel Anthracite 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 1 - 3 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 3L Anthracite Gravel 1-3Mm
