What’s the difference between sandbox and pool filter sand?
As your pool water flows down through this sand, debris and particulates as small as 20 to 100 microns in size get caught in between the tiny sand particles and filtered out of the water. At a size of up to 2 millimeters across, sandbox and play sand particles are much coarser and larger than pool sand.
What happens when you add de to a sand filter?
Adding DE to a sand filter will improve filtration but it does not filter as well as DE. What you are doing is filling the spaces between the grains and making them smaller so smaller particles get caught. A slightly dirty filter does the same thing so you are, in effect, dirtying the flter!

How does a sand filter work?
How Sand Filters Work. Sand filters work by allowing water to cycle through a canister that contains sand. The water flows through the sand with ease, but larger particles are unable to pass through. Once the debris and other particles have been filtered out by the sand, a pump moves the clean water back into the pool.
What is a pool filter cartridge?
Three Most Commonly Used Pool Filters Cartridge Filter – A Cartridge filter is a cylindrical filter that have a pleated filter material in which being pleated, maximizes the square footage of the filter. Cartridge filters can capture debris as small as 10-15 microns.
