Diatomaceous Earth is added to the filter through the skimmer while the pump is operating. It mixes with the water inside the skimmer and within the plumbing from the skimmer to the filter where, once inside the filter it coats the filter grids. Add 1 lbs. of D.E. (1 filled orange D.E. scoop) per each 10 square feet of filtration area of the filter. ................
