Compact Sieve 2
The Compact Sieve is a very versatile mechanical filter that can be used in different applications. As a particle remover directly next to the pond or to a waterfall/stream return to pond. As a mechanical particle waste pre-filter before surface mounted biological stages. As a mechanical pre-filter for existing trickle filter systems. The Compact Sieve can be connected to a pond vacuum cleaner and the returned water from the vacuum cleaner can be fed into the input hose tail via a T-piece or directly. For extra particle removal and saving your precious matured pond water. The Compact Sieve can be connected to an existing pumped pond skimmer system. The unit must be mounted above pond water level.

SuperSieve (Pump Fed)
SuperSieve (Pump Fed)
The SuperSieve Pump Fed system offers a straightforward solution for removing larger particles of dirt (over 0.2 mm) from pond water. Specifically designed for ponds where the pump resides within the pond itself, this system efficiently filters dirty water before it reaches a biological filter.
At the heart of the SuperSieve Pump is its specialized industrial curved screens. These screens consist of razor-sharp triangular rods angled in relation to each other, incorporating a precise 300-micron (0.3 mm) slit. As water flows against the sharp edges of the triangles, surface tension is broken, allowing dirt particles to be pushed away from the screen and lifted out of the water. The dirt then slides down the screen until it collects in the SuperSieve’s dirt gutter. Read more
Ultrasieve 3
Ultrasieve 3
The Ultrasieve 3 is the most compact, gravity fed, sieve filter with the highest pump capacity on the koi market! For years the Ultrasieve 3 has been the leading and most reliable pre-filter for professional koi ponds. The Ultrasieve 3 is supplied with an extra large waste outlet, including a slide valve 90/110mm! A few years after the introduction of the successful UltraSieve II it has been succeeded by the Ultrasieve 3. Most important features of the Ultrasieve III are the improved flow regulation and the new waste outlet which have fine tuned the overall performance.

Ultrasieve 3 Three Inlets
Ultrasieve 3 Three Inlets
UltraSieve filters are the most reliable pre-filters on the market. This is partly due to the simple design, with just one moving part. The pre-filter is not self-cleaning, but it is very easy to maintain. Open the slide valve and the debris can be washed away. The UltraSieve pre-filters have a stainless steel filter element that never needs to be replaced. Thanks to the triangular stainless steel rods at a 7° angle, the water falls directly through the sieve, but the debris remains. A major advantage of this principle is that the debris is truly removed from the water circulation. This is highly beneficial to the water quality, because waste products are no longer polluting the water.
