The AlphaONE 3" filters from Grand Champion Technologies (GCTek) features large 3" piping and unions to lower friction loss in these 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.
Omnifuser 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.
High surface area and flowrate for efficient filtration -- you don't need a very large pump!
Large 3" 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!
