About this product

Pool filter glass media removes 30% more material and pollutants than sand, the glass is heat treated so the smooth surface of the glass is less susceptible to pollutants, resulting in the need for less backwashing, which in turn lowers water, energy and chemical costs.

Less dense than sand, you require 20% less glass filter media to fill your filter, and as glass doesn’t degrade you can expect a longer life span, it is also suitable for both commercial and domestic applications.

Our glass media is Grade 1 (0.5mm to 1mm), which is equivalent to our grade 16/30 filter sand, so is suitable for use in all standard swimming pool filters and filter sets.

How much glass media do I need?

If your filter requires 50Kg of sand (two bags) then you will need 40Kg of glass media (two bags).

1 x 25Kg bag of sand = 1 x 20Kg bag of glass media

You should never mix glass media and sand in your filter

High purity

In contrast to other filter media, glass filter media is chemically inert, providing superior purity. In fact, it contains no crystalline-free silica or heavy metals.

The high purity also greatly reduces the initial backwashing requirements, enabling a rapid start-up of your filter.

Recycled

Raw material is taken directly from household recycling schemes and is 100% recycled glass. Using recycled glass achieves an environmental benefit over the use of natural resources.

Efficient

Glass removes more materials and pollutants than sand, saving on backwashing, water and chemical treatment costs.

Clean

Glass is less susceptible to bio-fouling, the heat-treated surfaces are smooth so require less remedial action and less chemical treatment to kill pollutants.

Long Life

Because the glass media has undergone a specialised heat treatment process, degradation is slower and the life span of the media is longer than sand.
