This is the 4.25 cu.ft. AlphaNANO unit. What a nice size filter. A 4.25 cu. ft. capacity designed to be used on ponds up to 10,000 gallons with fish loads up to a whopping 225 lbs. That's a lot of fish. Easily flows up to 90 gpm while only having a footprint of 24.5" X 36.5".
The AlphaNANO filters were designed to be the most energy efficient filters on the market. Inside is more than double the lateral surface area, where the upper beads gather around the slots in the exclusive Omnifuser, than that used on any other filter. Couple this with the highest flow multiport valve on the market and you have a filter that was designed to be energy efficient and perform to your exact expectations.
Set it up in an hour. Water’s been clear since.
I’ve been running the AlphaNANO 4.25 for about 14 months now. It’s handled my 9,000-gallon pond through all seasons. Backwashing is quick, and water clarity has stayed consistently high. Maintenance is almost nothing.
Easy setup, no clogs, and my koi are thriving. Really solid filter
