{"product_id":"aqua-ultraviolet-ultima-ii-filter-4000","title":"Ultima II Filter, 4,000, with 1-1\/2\" Valve DROP SHIP ONLY NO FREE FREIGHT","description":"This Ultima II Filter is a great choice for Koi ponds up to 4,000 gallons. This filter is specifically engineered to meet the environmental demands of fish ponds. The lightweight media is designed for very high flow rates. The tubular bio-media has low head loss and a very high biofilm surface. The \"Y\" shape on the inside and wings on the outside afford a protective surface under backwashing, and with our patented backwash system will keep the media from clogging. The same properties have been added to this media in three different sizes with random lengths and diameters to avoid stacking. The Ultima II tubular bio-media offers the highest surface area for growth of beneficial bacteria. No other backwashable pressurized filter compares. Cleaning the filter is done by internal jets. The Ultima II is also the ideal filter for aquariums where very high flow rates are desired. \n\u003cbr\u003e\u003cbr\u003e\n\u003ci\u003eFeatures:\u003c\/i\u003e\n\u003cul\u003e\n\t\u003cli\u003eDimensions (Diameter x Height): 20.5\" x 35\"\n\t\u003c\/li\u003e\n\t\u003cli\u003ePond Size: up to 4000 gal\n\t\u003c\/li\u003e\n\t\u003cli\u003eRecommend pump flow rate: 4,000 gph (at 10 ft. of head pressure)\n\t\u003c\/li\u003e\n\t\u003cli\u003e1-1\/2\" Inlet\/Outlets\u003c\/li\u003e\n\t\u003cli\u003eMax pressure: 38 psi\n\t\u003c\/li\u003e\n\t\u003cli\u003eTop Valve Mount\n\t\u003c\/li\u003e\n\t\u003cli\u003eIncludes media.
