The AlphaONE filter from Grand Champion Technologies (GC Tek) take all the features and benefits of the AlphaONE filter, and reduce the head to allow for lower restriction and higher flow rates.

Lower Head
These filters reduce water flow restriction by bypassing the multiport valve when in regular filtration mode. To complete the backwash cycle, simply move the two 2-way valves to direct water into the pipes. By not using the piping in normal filtration mode, you can use a smaller, more energy-efficient pump to do the exact same job.

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.

Omnifuser
AlphaONE filters can function for extended periods of time without slowing down. While utilize the Omnifuser design that picks up heavier solids in teh center of the bottom of the vessel. This prevents 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.

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, keeping the bacteria alive.

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!
  • Fiberglass body that is much more durable than plastic
  • Limited Lifetime Warranty on tank
