Ultrasieve's are the most compact, gravity fed, sieve filter with the highest pump capacity on the koi market.


For years the Ultrasieve has been the leading and most reliable pre-filter for professional koi ponds. 


Pond water will flow over the top of the auto-adjustable dam. This dam is connected to the float so its height is automatically adjusted. This system will ensure that the exact amount of water that is pumped out the filter will enter the filter on the inlet. 

Supplied with a 200 or 300 micron screen.

Simple to install and maintain. 

Also Perfect for Skimmer lines
