sera Gravel Brown is CO2 proof and neutral towards water, i.e. it has no influence on water parameters and does not tint the water. It consists of ground lava rock, and provides ideal space for settling by useful bacteria due to being open and porous. It is thus effective as a supportive natural biological filter medium. At the same time it provides plants with optimal preconditions for developing strong roots.
Due to its natural structure, the natural gravel is not suitable for keeping fish that search for food in the ground, such as Corydoras.
sera Gravel Brown 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.
sera Gravel Brown Lava consists of carefully selected, natural materials that are free of harmful chemicals and dyes. This makes it safe for all aquarium inhabitants, including fish, invertebrates and plants. Its special shape and structure also promote effective permeability and provide an ideal habitat for beneficial micro-organisms that contribute to biological filtration. In addition, Sera Aquarium Gravel supports plant health by providing a stable base for roots and allowing optimal nutrient circulation. This promotes plant growth and development, which in turn contributes to the overall quality and clarity of the aquarium water and minimises the risk of unwanted algae growth.
