 Aqua UV's Ultima II pond filter provides amazingly effective and efficient biological and mechanical filtration for Koi ponds. The Ultima II Pond Filter is specifically engineered to meet the environmental demands of ponds.
The lightweight media in the Aqua Ultima II is designed for very high flow rates. There is a patent pending on the tubular filter media which has low head loss and a very high biofilm surface.
The “Y” shape on the inside and wings on the outside affords a protective surface under backwashing and the patent pending backwash system will keep the media from clogging.
Please Use Appropriate Pump For Filter Size (I.E. if your pond is 2000 Gallons and you buy a 4000 Gallon Filter, use a 4000 GPH pump as Well)
