The AlphaONE 1.75 Filter is a high-performance filtration system designed for ponds up to 2,500 gallons. It utilizes advanced bio-mechanical filtration technology to ensure crystal-clear water and a healthy aquatic environment.
Key Features:
- Omnifuser Design Technology: Eliminates slotted PVC pipes, allowing heavier solids to settle at the bottom for easy removal during backwash.
- AlphaONE Life Support System (ALISS): Keeps beneficial bacteria alive during medical shutdowns or pump failures, maintaining biological filtration.
- HP Media Agitator: Breaks up debris and prevents clogging, ensuring efficient backwashing and reducing water usage.
- 2" Clear Union Spring Check Valve: Located beneath the blower, it provides maximum flow and includes built-in unions and a slide valve for added protection.
- Fiberglass Construction: Durable and rated at 50 PSI, ensuring long-lasting performance.
The AlphaONE 1.75 Filter offers an affordable solution for maintaining pristine water quality in smaller ponds. It is available for purchase through authorized dealers.
I like that the media doesn’t clog up fast, and backwashing is simple. Also, the ALISS feature really helps if the pump shuts off. Less stress about losing all the good bacteria. Solid unit overall.

Good filter. Easy to use and does the job well.
The AlphaONE 1.75 has been running on my pond for a few weeks. Setup was quick, and I haven’t had to do much since. The water’s stayed clear, and cleaning it is easy. Worth the price.
