AquaBead Filters

The AquaBead filter is the standard for bead filters and preferred by Koi enthusiasts and water garden professionals
All Grand Champion Technologies Aqua Bead Filters include a long list of desired standard features -

  • The AquaSwirl Internal Vortex is a unique circulation pattern that spins solids to the center of the filter where they cllect and are easily purged through the AquaBead Sludge Drain Valve
  • The AquaBead Bead Agitator is a dynamo powerhouse of air output! During backwash operation this 2 hp blower breaks up any beads that have packed together, allowing sludge to be flushed while beneficial bacteria is retained
  • ALISS is the AquaBead Life Support System. In the event of pump failure or system shut an air hose from an external pond pump can be attached to a one way valve mounted on the front of the multiport valve. This enables you to keep precious bacteria alive indefinitely.
  • The 2 Inch Clear Union Spring Check Valve is located right under the 2 HP blower provides maximum flow and has built-in unions
  • GC Tek stands behind their products with one of the strongest warranties in the business. Every AquaBead filter is backed with a Limited LIFETIME Warranty!

How Does GC Tek Size Their Filters?

University tests show that one cubic foot of media have approximately 450 square feet of surface area! This volume of surface will cultivate enough beneficial bacteria to manage the waste from 50 lbs of fish feeding on a daily diet equivalent to 1% of their body weight at 38% protein.

This formula is the basis for the pond size and fish load ratings GC Tek uses to size it's filters. In fact, GC Tek uses the more conservative end of the range to size their filters.

You can be confident when you use a GC Tek AlphaONE or AquaBead Koi pond filter, or a PondKeeper water garden filter, that you are providing a superior level of bio-mechanical filtration for your Koi pond or water garden.
