Glass media is an alternative to the normal sand grade media. Generally the glass is 100% recycled plate glass which is crushed, dried and screened to the correct size so it works at its best performance for your filter. Tests show that glass media catches more of the turbid particles than sand and helps to clean your swimming pool much more effectively.
Glass media also backwashes more quickly which helps to save from water loss and lost chemicals as well as saves on your pools heating costs.
Glass media is safe to handle because they are smooth and spherical.
