Sand Media. Silica sand is the oldest and most trusted media for sand filters. All sand is different, so don't trust just any old bag of sand. Silica is definitely the way to go. If you get number 20 silica sand, that means it will filter up to 20 micron particles (much much smaller than the human eye can see).
