The AlphaONE filter from Grand Champion Technologies (GCTek) is a revolutionary new filter featuring several innovations that improve its function over the already-effective AquaBead filters.

AlphaBioONE Filter Media
The real secret behind the AlphaONE filters is the AlphaBioONE filter media. While filter beads trap solids in the first few inches of the bead pack (causing clogging, flow disruption and rising pressure), AlphaBioONE media is uniquely designed to trap debris evenly across the entire filter. This effective change causes greater flow and less back pressure. This all leads to lower maintenance and higher effectiveness. This proprietary filter media was specifically developed to have fewer areas that collect anaerobic bacteria, leading to greater beneficial bacteria activity.


AlphaONE filters can function for extended periods of time without slowing down. Omnifuser technology means that heavier solids are picked up from the center of the bottom of the vessel, preventing the filter from building up solids. These solids can then be drained during the backwash cycle. This filter doesn't hold solids -- it gets rid of them. Furthermore, because water enters the lowest point and exits the highest point of the tank, all of the filter media is utilized for maximum filtration.

Life Support System
The AlphaONE Life Support System (ALISS) is designed to keep bacteria alive if you ever have to do a medical bypass, or if your pump fails. A one-way valve on the front of the multiport valve allows air in without letting water seep out! Simply hook up an air pump to the barbed fitting, and air will flow into the filter, gently tumbling the media and keeping the bacteria alive.

The AlphaONE Agitator prevents the filter beads from sticking together. When this 2 HP pump kicks into action, air is injected into the bottom of the filter, which breaks up the clumped beads as it rises violently to the top.

Additional Features
  • High surface area and flowrate for efficient filtration -- you don't need a very large pump!
  • Large 2" spring check valve allows for high flow, and dual unions make replacing simple
  • Side-mounted valves and a top opening means you don't need to unhook the plumbing!
  • 10" clear lid on tank and sight glass on multiport valve makes filter inspection easy
  • Double-layered fiberglass body is immensely more durable than plastic
  • Pressure gauge tells you what is going on inside tank
  • Easy drain allows water to exit, but not filter media!
  • Limited Lifetime Warranty on tank

NOTE:  Genuine replacement media is available by the Cubic Foot.   

Four cubic feet of replacement media is needed for the AlphaOne 4.25
