Davey Crystal Clear Glass Media is a finely crushed, 100% virgin recycled glass for filtration use in both residential and commercial pools. Crystal Clear Glass Media has the capacity to remove iron and magnesium, making it suitable for pools topped up from a groundwater supply. The clarity of water filtered with glass is comparable to water filtered with DE.
Bacteria cannot grow in this glass media. The smooth angular surface of the glass granules does not house fungi or moss, creating a healthier swimming environment.
It is claimed that Davey Crystal Clear Glass Media cuts chemical usage by up to 50% due to the self-sterilisation nature of the glass and an oxidation process that takes place when water passes over the glass. Additionally, better permeability results in up to 25% less water to backwash over the period of a year.
