DE Filter Powder Calculator - How Much DE to Add?
Calculate exactly how much Diatomaceous Earth (DE) powder to add to your pool filter after a backwash or deep cleaning. Find the correct amount in lbs and scoops.
What is a DE Scoop?
Standard DE scoops are designed to hold exactly **1 lb of DE powder**. However, it is always a good idea to weigh your first scoop to ensure your brand of DE doesn't have a different density.
Note: Never run a DE filter without the powder. The DE is what does the filtering; without it, dirt will clog your expensive filter grids instantly.
Frequently Asked Questions
Can I use sand instead of DE powder?
No. Sand is too large and will not work in a DE filter system. It would likely pass right through the grids and back into your pool.
What is DE powder made of?
Diatomaceous Earth is made from the fossilized remains of tiny aquatic organisms called diatoms. Their skeletons are made of silica and act as incredible micro-filters.
