New in 2022!

GC Tek has taken the super popular AlphaOne and AquaBead line of filters and have added their new NANO media to them which even further increased the surface area to now over 600 Square feet per cubic foot which delivers rich colonization of beneficial bacteria to clean and polish your pond. 

Customer Feedback is unanimous "We Love the performance of these units!" And we, at Play It Koi, love these GCTek 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 desirable? with the smaller AlphaNano beads, this filter works as good as a polishing filter as it does a Biological filter! The Alpha Nano media has about 50% more surface area for Beneficial Bacteria to grow than a Bead Filter has for surface area.

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 AlphaNANO 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 AlphaNANO with its uniquely designed AlphaNANO 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 its most desirable features, based upon comments that have come into us from the field.

The AlphaNANO media was specially designed for this filter. It is not something borrowed from another industry or use. 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 AlphaNANO media, there are no hidden areas for anaerobic bacteria, to harbor and stagnate, only beneficial bacteria.

Take a look at the AlphaNANO media and you'll see for yourself.
