Evolution Aqua Cetus Sieve

High Performance Mechanical Pre Filter for Gravity and Pump Fed Systems

The Evolution Aqua Cetus Sieve is a high performance mechanical pre filter designed to remove solid waste before it reaches your main filtration system. Suitable for both gravity fed and pump fed installations, it significantly improves filtration efficiency while reducing maintenance requirements. As a result, it helps maintain cleaner water and more stable pond conditions.

Designed for koi ponds and larger systems, the Cetus Sieve captures debris such as leaves, fish waste and uneaten food before it enters biological or pressurised filters. Therefore, it protects downstream equipment and improves overall system performance. In demanding pond environments, this makes a noticeable difference to water clarity and long term reliability.

With a maximum flow rate of 18,000 litres per hour, the Cetus Sieve is ideal for medium to large koi ponds. Consequently, it is widely used in both residential and professional pond builds where effective mechanical filtration is essential.

Efficient Mechanical Filtration with 300 Micron Screen

At the heart of the Cetus Sieve is a 300 micron wedge wire screen made from high grade stainless steel. This screen captures solid waste while allowing clean water to pass through into the filtration system.

Because of the fine screen size, it removes a high percentage of suspended solids before they reach biological media. As a result, it reduces clogging and improves the efficiency of the entire filtration setup.

In addition, the wedge wire design prevents debris from passing through or becoming embedded. Therefore, waste can be removed quickly and easily during cleaning.

Patented Pondflow System for Consistent Operation

The Cetus Sieve features a patented Pondflow system with a self adjusting weir. This system automatically maintains a consistent water level inside the unit.

As pond water levels fluctuate, the weir adjusts accordingly. Therefore, flow rates remain stable and filtration performance is not affected.

This makes the Cetus Sieve particularly effective in gravity fed systems, where maintaining correct water levels is essential for reliable operation.

Flexible Installation for Gravity and Pump Fed Systems

The Cetus Sieve can be installed in both gravity fed and pump fed configurations. This makes it suitable for a wide range of pond designs and filtration layouts.

In gravity setups, the unit is installed at pond water level and fed directly from a bottom drain or skimmer. In pump fed systems, water is pumped into the sieve before passing through to the main filter.

Because of this flexibility, the Cetus Sieve is a popular choice for both new builds and filtration upgrades.

Durable Construction and Low Maintenance Design

The unit is manufactured from a one piece moulded body, eliminating joints and reducing the risk of leaks. This ensures long term durability in outdoor pond environments.

The stainless steel screen is easy to clean, and collected waste can be flushed away quickly. As a result, maintenance is simple and takes minimal time.

By removing solids early in the filtration process, the Cetus Sieve also reduces the need for frequent cleaning of biological and pressurised filters. Therefore, it helps extend the lifespan of your entire filtration system.
