Silica sand is the oldest of the filtering medias Not all sand is created equal and if you are going to replace your old media with sand silica sand is the way you need to go Number 20 silica sand will filter down to 20 microns As you can see from our chart above it will take care of most suspended solids in the pool waterNov 12 32 To a geologist or mineralogist “silica” only means a SiO2 compound regardless of its actual crystal structure If you had pure SiO2 glass you could describe it as being made of silica and you can say that chemically pure quartz is also SiO2
