The only correct way to measure one pound of DE (diatomaceous earth) is with a DE Scoop. The orange Hayward® DE Scoop measures exactly one pound of DE (one orange scoop = one pound DE). Use this chart to determine how many scoops of DE you need. Check the manufacturer's sticker on the side of your DE filter or review the owner's manual if you're not sure of the size of your DE pool filter.
