Aquaforte Ultraseive III
The Ultrasieve III is the most compact, gravity fed, sieve filter with the highest pump capacity on the koi market! For years the Ultrasieve III has been the leading and most reliable pre-filter for professional koi ponds. The Ultrasieve III is supplied with an extra large waste outlet, including a slide valve 90/110mm!
This has a number of big advantages in comparison with other sieve filters:
Multiple, or bigger, inlets are possible (standard 2 x 110mm!).
The upper edge of the UltraSieve must only be 1 cm above the water level.
Reduced cost thanks to the simple floating system.
Pump speed up to 4000gph
