We recommend Zeolite as a filter medium. Zeolite has some significant advantages over sand:

  • filters up to 10 times smaller particles
  • considerably lower use of chlorine (50 to 75% less)
  • 50% fewer backwashing cycles required
  • typical chlorine smell reduced considerably
  • removes ammonium from the water
  • volume 15 kg zeolite = volume 30 kg sand
