AlphaONE - More than a Bead Filter! Customer Feedback is unanimous "We Love It"! And we, at Play It Koi, love the AlphaOne filter units so much that this is what we choose and trust to run on our show pond! What makes it different from a bead filter and so loveable? One reason is that these units can go for greatly extended times before flow slows down. Much longer than normal filtration. How does it do this?To answer this we have to understand the difference between bead filters and how they trap solids and how the AlphaONE accomplishes this task. Bead filters trap solids in the first few inches of the bead pac (causing clogging, flow disruption, and pressure rises in the vessel) while the AlphaONE with its uniquely designed AlphaBioONE media stops the debris evenly throughout the pac (resulting in greater flow, less head or back pressure, less maintenance.) The polishing ability of the filter is one of it's most desirable features, based upon comments that into us from the field. The AlphaBioONE media was specially designed for this filter and this filter only. It is not something borrowed from another industry and used in the filter. Its design is unique in that it was not designed with "crosshairs" as some other specialty types of media use. We left those out because in a static bed the "crosshairs" can collect and hold debris until it becomes anaerobic. With the AlphaBioONE media, there are no hidden areas for anaerobic bacteria, to harbor and stagnate, only beneficial bacteria. Take a look at the AlphaBioONE media and you'll see for yourself... University tests have shown that a cubic foot of beads that have 400 - 450 cu. ft. of surface area will handle 50 lbs. of fish being fed 1% body weight per day @ 38% protein. This is the formula that we use, even though our beads have 500 to 550 sq. ft. of surface area per cu. ft. and in theory should do more, we refuse to stretch or make claims beyond what has truly been tested.

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. GCTek products are not eligible for order discounts. All GCTek filters are built-to-order, and fulfillment timing varies based current order volume. Ships freight, which extends shipping time and requires you to be present at delivery. Trucking company will call to schedule appointment. Documentation AlphaONE Filters — Installation Guide (PDF) Product Video
