AlphaONE: more than a bead filter
Customers tell us they love these filters. We do too: the AlphaONE is the filter we chose to run on our own show pond.
What sets it apart from a bead filter? It can run much longer before the flow starts to slow.
How does it do this?
A bead filter catches most of its solids in the first few inches of the bead bed. That layer clogs, which cuts flow and raises the pressure inside the vessel. The AlphaONE's AlphaBioONE media catches debris evenly through the whole bed, so water keeps moving, there's less back pressure, and you clean the filter less often. Owners tell GC Tek the polishing is one of the things they like most about it.
GC Tek designed AlphaBioONE media for this filter alone. Some specialty media have internal crosshairs, and in a static bed those crosshairs hold debris until it goes anaerobic. GC Tek left them out, so there are no hidden pockets for debris to sit in.
GC Tek sizes the AlphaONE on university test results: a cubic foot of beads with 400 to 450 square feet of surface area handles 50 lbs of fish fed 1% of their body weight a day on 38% protein food. AlphaBioONE media has 500 to 550 square feet per cubic foot, so in theory it could handle more, but GC Tek rates it on the tested figure.
Here's a close look at the media.

| Fish load ratings assume fish fed at 1% of body weight daily. The model number is the volume of media the filter holds, in cubic feet. On the 6.3 and 10.3, the trailing .3 indicates a larger plumbing size rather than additional media, which is what allows the higher flow rate. | |||||
