The 1.75 cu.ft. AlphaONE is a big workhorse in a small package. The 1.75 cu. ft. model is rated for ponds up to 2500 gals. with flow rates not over 50 gpm for bio-mechanical filtration. The 1.75 can handle fish loads of 87.5 lbs. Comes complete with all 2" threaded fittings for maximum flow and all the "Bells and Whistles" of the larger units. Tank measures 19" X 30".
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 "cross hairs" as some other specialty types of media use. We left those out because in a static bed the "cross hairs" 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.
The AlphaBioONE media comes in two shapes mixed together and as the media nests together in its pac tremendous amounts of solids can be trapped within the pac without going anaerobic and still function biologically to perform its second job of nitrification. The solids are easily dispersed when the media agitator is engaged to break up the pac and release the solids out to backwash. Each shape has specially designed ridges around the outside to promote beneficial bacterial growth, but not so long as to cause the media to interlock. Interlocking media, used on some filters, does not come apart when agitated. The shorter, more optimal ridge feature was carefully designed and tested to make sure the filter would function perfectly in the long run.
The internals on the AlphaONE, slightly different than the AquaBead filters, are designed to give maximum flow, the least maintenance and the lowest possible head loss of any filter of its type. With the internals using larger slotted openings on the AlphaONE we don`t need a sludge drain to rid the filter of sludge, this is accomplished doing a normal backwash of the filter. This also makes the filter a little more user friendly and quicker to backwash.
Quicker cycling than bead filters has been reported by many in the field. Some reports of 10 - 14 days have been reported. Compare this with 4 - 8 weeks with most bead type filters.
