DE Diatomaceous Earth (for DE Filters)

$39.99

Achieve professional-grade water clarity with our 25 lb. Diatomaceous Earth (D.E.) Filter Powder. This all-natural media is designed for use in all D.E. pool and spa filter systems, providing the highest level of filtration possible by removing particles as small as 2 to 5 microns.

D.E. powder works by coating your internal filter grids with a porous, sponge-like layer that traps microscopic contaminants, dirt, and even certain types of bacteria that sand and cartridge filters often miss.

D.E. Powder Dosage & Coverage

Proper measurement is critical. Adding too little can leave grids unprotected, while adding too much can cause "bridging" between grids, reducing efficiency.

Filter Size (Sq. Ft.) Full Charge (New/Cleaned Grids) Recharge (After Backwashing)
24 sq. ft. 2.4 lbs (approx. 5 scoops) 1.9 lbs (approx. 3 scoops)
36 sq. ft. 3.6 lbs (approx. 7 scoops) 2.8 lbs (approx. 5 scoops)
48 sq. ft. 4.8 lbs (approx. 10 scoops) 3.8 lbs (approx. 7 scoops)
60 sq. ft. 6.0 lbs (approx. 12 scoops) 4.8 lbs (approx. 9 scoops)
72 sq. ft. 7.2 lbs (approx. 14 scoops) 5.7 lbs (approx. 11 scoops)

Note: 1 lb. of D.E. powder is roughly equivalent to a 1 lb. coffee can or two 1/2 lb. D.E. scoops.


How to Apply D.E. Powder

For the best results and to prevent clumping, follow these steps:

  1. Backwash the Filter: Always start by backwashing the system to remove old, dirty powder.

  2. Mix a Slurry: In a bucket, combine the required amount of D.E. powder with pool water to create a thin, creamy mixture.

  3. Add via Skimmer: With the pump running, slowly pour the slurry into the skimmer closest to the filter.

  4. Monitor Pressure: Check your filter's pressure gauge. It should rise to the normal operational range (typically 10-15 psi) once the grids are fully coated.
