The Cetus sieve is a totally new, bow screen pre-filter, made using the latest rotational molding technology. The Cetus sieve is a bow screen pre-filter, suitable for pre-filtration of any biological filter, including all pressure filters. It is advised that all pressurized filters be pre-filtered using a Cetus to reduce excessive back-washing and maintenance due to heavy solids. It is designed to efficiently and effectively remove large amounts of mechanical waste from a pond. It includes the necessary parts to set it up to be gravity-fed OR pump-fed and has many benefits.
Gravity Fed: This Cetus has a variable inlet height using the unique patented Pondflow regulation system. 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 (such as the Nexus™ or EazyPod™) or to a pressurized filter (such as the K1 Micro Bead Filter)
Pump Fed: The sieve is placed above pond water level and then the exit water is gravity dropped into your main filter.
Plug and Play – comes with flexible boots to connect to pipe work
Greatly reduced backwashing and maintenance of pressurized filters
Robust one-piece mold is totally reliable
Large waste collection area which slopes to 3" waste outlet
Patented float that gives constant flow for gravity-fed level fluctuations
Tri-slot 300 micron wedge wire screen in 316L stainless steel prevents waste from bypassing
Increased levels of oxygen
Measures 33.5" x 22.4" x 37.2"
Maximum Flow Rate
