All of the AlphaONE filters utilize the Omnifuser design technology that eliminates slotted PVC pipes in the filter. The Omnifusers allow the heavier solids to be easily purged from the bottom of the filter during backwash since they are sitting at the lowest point in the filter.

The 2.50cu.ft. AlphaONE is the perfect filter for ponds up to 5000 gal. and fish loads up to 125 lbs. Flow rated at 70 gpm for bio-mechanical filtration. 21" X 34.5" allows you to hide this unit anywhere. Every option is standard equipment. The perfect filter for the majority of ponds.

AlphaONE filters also feature the AlphaONE Life Support System, known as "ALISS", which keeps beneficial bacteria alive indefinitely during times of medical shutdowns, pumps failures, etc.

The 2" Clear Union Spring Check Valve located right under the 2 HP blower provides maximum flow and has built-in unions and a PVC slide valve for extra blower security.
