Evolution Aqua Cetus Sieve - FREE SHIPPING

We are back in love with the Cetus - but only as a standalone sieve (not trying to balance it on a single gravity bottom drain and then push onto another filter system). When you reconsider the Cetus, you realise that it is an extremely affordable sieve option considering the premium construction. 

Expertly engineered for maximum efficiency, the Evolution Aqua Cetus Sieve offers a maximum flow rate of 18,000 liters/hr or 4,000 UK gallons/hr, making it the perfect solution for both gravity and pump fed systems. With a 110mm/4" inlet for gravity systems and a 50mm/1½" inlet for pump systems, this sieve ensures optimal filtration for your aquatic needs. Trust in the objective and scientific design of the Cetus Sieve for a cleaner and healthier aquatic environment.

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.
