Cetus Sieve



The Cetus sieve is a great concept, with 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, regarding 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.
300 MICRON SIEVE screen on 100% of surface area
This Cetus comes with 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 which can ofcourse cause some major problems. The Cetus will allow a skimmer or a bottom drain to accept vast amounts of waste without excessive cleaning needed to be carried out. (Always a bonus for the busy fish keeper)! The water must then be pumped to either a normal filter above pond level (Nexus Eazy/Eazy Pod) or to a pressurised filter.


·        Perfect fit screen so no waste can bypass
·        Totally reliable and simple to install
·        Plug and Play – comes with flexible boots to connect to pipe work
·        Greatly reduced backwashing / maintenance of pressurised filters
·        Robust one piece mould –no welded joints – no leaks!
·        Large waste collection area which slopes to sump outlet
·        Ideal for mechanically filtering skimmer lines
·        Patented float that gives constant flow for gravity-fed level fluctuations
·        Maximum flow rate 18,000 litres per hour
·        Tri-slot 300 micron wedge wire screen in 316L stainless steel on 100% of surface area
·        Increased levels of oxygen
