    INTRODUCING THE CETUS SIEVE Congratulations on purchasing an Evolution Aqua Cetus Sieve. The Cetus Sieve is a bow screen pre-filter, made using rotational molding technology. It is designed to efficiently and effectively remove large amounts of mechanical waste from a pond and can be installed on a gravity fed set-up or a pump fed set-up.
