{"title":"Pond Sieves \u0026 Sieve Pre-Filters","description":"\u003cp\u003ePond sieves use a fine static screen to separate solid waste from your pond water before it reaches the pump and biofilter. Gravity-fed and pump-fed sieve pre-filters deliver RDF-style solids removal with no moving parts — an efficient, budget-friendly first stage for koi ponds that keeps your pump protected and your water clear.\u003c\/p\u003e","products":[{"product_id":"cetus-sieve-prefilter","title":"Cetus Sieve","description":"\u003cp\u003eThe Cetus 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.\u003c\/p\u003e\n\u003cp\u003eThis 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 (AquaBead\/AlphaONE).\u003c\/p\u003e\n\u003cp\u003eIf pump fed, the sieve is placed above pond water level and then the exit water is gravity dropped into your main filter.\u003c\/p\u003e\n\u003cp\u003eIt is advised that all pressurized filters be pre-filtered using a Cetus to reduce excessive backwashing and maintenance due to heavy solids.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eCan be gravity or pump fed\u003c\/li\u003e\n\u003cli\u003ePerfect fit screen so no waste can bypass\u003c\/li\u003e\n\u003cli\u003eTotally reliable and simple to install\u003c\/li\u003e\n\u003cli\u003ePlug and Play - comes with flexible boots to connect to pipework\u003c\/li\u003e\n\u003cli\u003eGreatly reduced backwashing\/maintenance of pressurized filters\u003c\/li\u003e\n\u003cli\u003eRobust one-piece mold -no welded joints - no leaks!\u003c\/li\u003e\n\u003cli\u003eLarge waste collection area which slopes to sump outlet\u003c\/li\u003e\n\u003cli\u003eIdeal for mechanically filtering skimmer lines\u003c\/li\u003e\n\u003cli\u003ePatented float that gives constant flow for gravity-fed level fluctuations\u003c\/li\u003e\n\u003cli\u003eMaximum flow rate 18,000 litres per hour\u003c\/li\u003e\n\u003cli\u003eTri-slot 300 micron wedge wire screen in 316L stainless steel on 100% of the surface area\u003c\/li\u003e\n\u003cli\u003eIncreased levels of oxygen\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv style=\"overflow-x: auto;
