This environmentally friendly filter media is made from glass recycled in the UK. It is a viable alternative to sand and does not involve intrusive mining and the use of scarce resources. It is available in three grades – all grades are milled down to remove sharp points and are packed in 25kg bags.

Glass media is more efficient than sand as it can remove up to 30% more material and pollutants than sand, saving on backwashing and the resulting water, energy and chemical treatment costs. It also doesn’t degrade so it has a longer life span.

Use in place of traditional filter media.

  • Grade 1 is equivalent to 16/30 grade sand;
  • Grade 2 is equivalent to 8/16 grade sand;
  • Grade 3 is equivalent to 6mm gravel.

  • Resists bacterial contamination
