The Aladdin E-Z Scoop is the perfect way to add DE to your filter from the bag or box. Each scoop will add the industry standard scoop for diatomaceous earth. For vertical filters, use one full scoop per 5 sq ft, and in bump filters, use one full scoop per 7-1/2 sq ft. Make sure that your filters always have a proper coating of DE to make sure that your pool water is properly filtered.
