The Evolution Aqua Cetus sieve is a bow screen pre-filter, made using the latest rotational molding technology. With all of its benefits and build quality, the EA Cetus Sieve is undoubtedly the best of its kind on the market today, regarding quality and performance. The Cetus Sieve has been designed to efficiently and effectively remove large amounts of mechanical waste from a pond. The Sieve can be set-up gravity or pump fed and has many benefits over the original bow screen technology.

This Cetus Sieve has a variable inlet height using the unique patented Pond flow regulation system – for when gravity fed. This allows water levels within the pond to drop without causing the circulating pump to be starved of water. The EA Cetus Sieve 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 such as Nexus Eazy or Eazy Pod or alternatively to a pressurised filter such as the EA K1 Micro Bead Filters.

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

The Cetus sieve is a bow screen pre-filter, suitable for pre-filtration of any biological filter including all pressured filters. It is advised that all pressurised filters be pre-filtered using a Cetus to reduce excessive back washing and maintenance due to heavy solids.
