The effectiveness of a DE pool filter depends entirely on the quality of the diatomaceous earth used to coat the filter grids. Low-grade or contaminated DE can reduce filtration efficiency, clog grids unevenly, and shorten filter life. Dicalite 10 lb DE Pool Filter Powder is a high-purity, NSF-certified diatomaceous earth media designed specifically for swimming pool filtration systems that require precise, fine-particle removal.

When added after backwashing, Dicalite DE forms a uniform filtration layer on DE filter grids, allowing the filter to trap microscopic debris while maintaining proper flow. This results in noticeably clearer water, improved circulation efficiency, and more consistent filter performance between cleanings.

This is true pool-grade DE filtration media—not agricultural or industrial DE repurposed for pool use.

Why DE Quality Matters in Pool Filtration

DE filters are capable of the finest filtration available in residential pools, but only when the DE media itself is consistent and clean. The powder creates the filtration surface—if it’s uneven, contaminated, or low quality, performance suffers immediately.

Using high-quality DE helps:

• Capture particles down to 2–5 microns

• Maintain even grid coating

• Prevent premature pressure rise

• Improve water clarity after backwashing

• Extend the life of DE grids

Dicalite DE is engineered to provide predictable results every time the filter is recharged.

NSF-Certified for Pool Filtration Use

NSF certification ensures the DE meets strict standards for pool and spa filtration applications. This matters because not all diatomaceous earth products are approved for use in swimming pools.

Using NSF-certified DE ensures compatibility with residential and commercial DE filters and helps avoid issues caused by impurities or inconsistent particle sizing.

Designed for All DE Pool Filters

Dicalite DE powder is compatible with all standard DE pool filters, including systems from major manufacturers. It disperses easily when added through the skimmer and coats grids evenly for immediate filtration performance.

Whether you’re maintaining a residential pool or servicing multiple systems, consistent DE quality makes filter servicing more reliable and repeatable.

When to Add DE Filter Powder

DE powder should be added:

• After every backwash

• When pressure returns to clean-filter baseline

• After cleaning or replacing DE grids

• During routine filter maintenance

Using the correct amount of DE for your filter size is critical for optimal performance.

Practical Filtration Media for Pool Owners and Service Professionals

For pool owners, Dicalite DE helps maintain crystal-clear water with less frequent filter issues. For service professionals, it provides predictable performance and consistent results across multiple filter systems.

Clean DE means clean water—and fewer filtration headaches.
