Superior Filter Media

Manufactured from pure glass, Glass Bead Media are a new generation of filter media, capable of providing water of superior clarity. Its spherical shape results in low coefficient of friction, reducing backwash requirements, saving pond owners both time and water.

  • 3 micron filtration
  • 20% less backwash water
  • High purity
  • Safe and smooth
  • Time saving
  • 0.6mm to 0.8mm in size

Superior Clarity

Glass Bead Media have a small effective size of only 0.6mm to 0.8mm. Its narrow particle size range allows in-depth filtration and extends operating cycles between backwashing. Glass Bead Media have been laboratory tested to be able to effectively filter down to below 3 microns.

Save Water

Glass Bead Media's spherical smooth shape, results in a low coefficient of friction, reducing its backwash water requirements. Glass Bead Media backwashes with up to 20% less water than sand, saving time and water.

High Purity

Glass Bead Media are manufactured from pure glass and chemically inert. Glass Bead Media have been independently lab tested for leeching contaminants and found to be well within Australian Drinking Water Guidelines.

Safe and Smooth

Glass Bead Media are spherical and do not have any sharp edges. They are safe to handle and safe to service. If there is ever a failure of the filter's laterals and Glass Bead Media flow into the pond they pose no risk of injury to fish.

Time Saving

Glass Bead Media are easy to install and enables a rapid start up of the media filter. Its high purity means very little backwashing is required to cleanse the filter media, prior to commissioning the filter.
