Koi Gravel Filter Media

Our Koi Gravel Filter Media is specifically selected and graded to deliver optimal mechanical and biological filtrationfor koi ponds, ornamental fish ponds, and aquaculture systems. Designed to work seamlessly with gravel bed filterslike the BADU Koi Filter Range, this natural media supports the development of beneficial bacteria colonies, essential for maintaining ammonia, nitrite, and nitrate balance in aquatic environments.

Each batch of gravel is washed, graded, and sieved to ensure uniform size and porosity, promoting excellent water flow while trapping fine suspended solids. Its inert and non-toxic composition ensures it’s safe for koi and aquatic plants, while also providing a stable foundation for long-term biological filtration.
