Can a sand filter cause a cloudy pool?
Another common reason why pool water turns cloudy is a build up of fine particles in the water. At their very best, sand filters only filter down to around 20 microns. As these particles build up they will cause the water to look cloudy.

What is pool sand made of?
Most play sand is made of quartz, also known as silica. The percentage of silica will depend on where the sand came from and how it has been treated.
