Evolution Aqua Cetus Sieve II

Cetus Mark II

The Cetus Mark II sieve is a totally new, bow screen pre-filter, made using the latest rotational molding technology. With all of its benefits and build quality, it is undoubtedly the best of its kind on the market today in terms of quality and performance! It is designed to efficiently and effectively remove large amounts of mechanical waste from a pond. It can be set-up gravity or pump fed and has many benefits over the original bow screen technology.

This Cetus has a variable inlet height using the unique patented Pondflow regulation system – for use when gravity fed. This allows water levels within the pond to drop without causing the circulating pump to be starved of water. The Cetus will allow a skimmer or a bottom drain to accept vast amounts of waste without excessive cleaning needed to be carried out. The water must then be pumped to either a normal filter above pond level (Nexus Eazy/Eazy Pod) or to a pressurized filter.

If pump fed, the sieve is placed above pond water level and then the exit water is gravity dropped into your main filter.

It is advised that all pressurized filters be pre-filtered using a Cetus to reduce excessive backwashing and maintenance due to heavy solids.
