Pre-filter to remove waste & debris
The Cetus sieve is a 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.
Overview
The Cetus Sieve is a self-adjusting sieve which can be installed either gravity fed or pump fed. The Cetus Sieve enables your pond water to be filtered of large amounts of waste and debris before the water enters your current filter system. This process is commonly referred to as “pre-filtering”. The Cetus Sieve can also be used as a stand-alone unit to remove leaves and other floating debris from your pond via a surface skimmer. The Cetus Sieve will efficiently and effectively remove large amounts of mechanical waste from your pond. The Cetus Sieve is compatible with all filtration systems, however it is the perfect prefilter for the Evolution Aqua Nexus filter range. For gravity fed systems the Cetus Sieve has a weir which will automatically adjust to the flow rate of your pump. (Max flow rate 18,000 litres/hr) When the Cetus Sieve is used in front of any other biological/mechanical filter the period in between cleaning will be extended. The biological process is improved by the removal of organic matter which would consume oxygen and leach ammonia and other compounds into the water.

How the Cetus Sieve works
Installing the Cetus Sieve The Cetus Sieve 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 pressurised filter.
If pump fed, the 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 backwashing and maintenance due to heavy solids.

Frequently asked questions
Can the Cetus Sieve be used on both pump and gravity fed systems?
Yes, the Cetus can be used on both gravity and pump fed systems. You simply swap the rubber boots around on the inlet/outlet
Can the Cetus Sieve be used as a stand alone filter?
No, The Cetus Sieve is a mechanical filter only, it has no biological filtration.
What kind of filter works best with the Cetus Sieve?
The Cetus Sieve is suitable for use with both pressurised filters such as the K1 MicroBead, and non-pressurised filters such as the Nexus, the Cetus Sieve can be used with most brands of filter following the same installation procedure as outlined in the manual for the Nexus.
Can I install a Cetus Sieve and a K1 MicroBead filter on a pump fed system?
No, the Cetus will need to be gravity fed to install before a K1 MicroBead filter.
Does the Cetus Sieve need to be installed above the water level?
If the Cetus Sieve is installed on a gravity fed system it will need to be level with the surface of the pond (please refer to the manual). If the Cetus Sieve is installed on a pump-fed system it will need to be above the surface of the pond, if not it would overflow (please refer to the manual)
Why do you need balance pipe?
If the Cetus Sieve is installed on a system with a biological filter such as a Nexus, the balance pipe ensures that neither the Cetus or biological filter do not overflow.
Why do i need two pumps?
If the Cetus Sieve is installed on a system with a biological filter such as a Nexus, you will need two pumps to install the Cetus Sieve as recommended, this ensure the optimal performance of both the Cetus and biological filter. If the Cetus is gravity fed you could use one pump but this would mean the biological filter would be raised above the pond. Only one pump is required if using with a pressurised biological filter such as a K1 MicroBead, the Cetus MUST be gravity fed.

Due to a large amount of leaf litter in my pond, I decided to get a Cetus Sieve pre filter, the quality, ingenuity of this prefilter, makes your pond maintenance so easy. I even decided to buy a second unit.
