We recommend the following 2 options as filter medium for your swimming pool's sand filter.
SILICA POOL FILTER SAND 40KG
Silica sand is commonly used in most pool filters. It is extracted and sifted to a particle size of between 0.6mm to 1.5mm
The sand's small, angular particles trap dirt and debris as water flows through the filter. It thus captures dirt and debris mechanically and it is washed out of the sand during the 'backwash-and-rinse' cycle.
THE SUPERIOR ALTERNATIVE IS CLINOBRITE:

What is the chemical effect of using CLINOBRITE?
Clinobrite is a specific type of Zeolite mineral mined in South Africa.
It is a direct substitute for pool filter sand that saves you money by scavenging unwanted ammonia from pool water and thereby reducing your swimming pool chlorine consumption. It is a true 21st century filter medium with both ion exchange and superior micro-filtration properties.
Unlike silica filter sand, the surface of Clinobrite grains are not smooth. Clinobrite grains attract and trap extremely fine dirt particles and algae onto their surface and not just between the grains like ordinary sand. In practise, a Clinobrite pool filter can remove 40 - 50% more physical dirt than an outdated sand filter. It can also filter out much smaller particle sizes than sand. This greatly improves the clarity of your pool and gives much longer service cycles between backwash operations. Clinobrite is even able to trap the tiny cysts of diarrhea causing cryptosporidium which are becoming a health problem in municipal waters worldwide!
Also, unlike sand filters, Clinobrite acts as a filter on the atomic scale by absorbing ammonium ions (NH4+) from pool water and this consequently eliminates algae. This is due to a powerful negative charge that exists within the Clinobrite structure that attracts positively charged cation contaminants such as ammonia and holds them within the Clinobrite structure.
Reduce Chlorination Costs
Clinobrite is a natural zeolite and a direct substitute for filter sand.
Unlike sand, Clinobrite will reduce chlorination costs by minimising ammoniacal nitrogen in swimming pool water.
