25lbs. Diatomaceous Earth Powder
Product Overview
Celatom Diatomite Filter Media is the standard specification for achieving the highest possible water clarity by trapping particles as small as 2–5 microns.
This 25 lb bag of Celatom Diatomaceous Earth (DE) powder provides a proven choice for homeowners who prioritize precision filtration over standard sand or cartridge systems. Sourced from natural fossilized diatoms, this 25 POUNDS supply creates a fine, porous coating on filter grids to capture microscopic debris, oils, and pollen. Because it removes contaminants that other media miss, it reliably handles the fine particulates that cause persistent cloudiness in residential and commercial pools.
Benefits & What Makes It Different
2–5 Micron Filtration
While sand filters typically trap particles at 20-40 microns, this 25lbs powder captures debris down to 2-5 microns for superior clarity.
25 POUNDS Bulk Supply
This 25 lb bag provides enough media for multiple recharges after backwashing, making it a staple for seasonal maintenance.
Natural Fossilized Diatoms
Celatom uses high-quality diatomite to ensure a consistent, porous layer that won't clog grids prematurely when used correctly.
Compatibility
- DE (Diatomaceous Earth) Filter Systems
- Residential and Commercial Pools
When To Use This
Pro Tip
Always mix the DE powder into a thin slurry with water in a bucket before pouring it slowly into the skimmer to prevent 'clumping' and ensure an even coat on the grids.
Common Questions & Instructions
How much 25 lb DE powder should I add to my filter after backwashing?
Generally, you should add 80% of the initial charge recommended by the filter manufacturer, typically measured in 1 lb scoops through the skimmer while the pump is running to ensure the grids are fully coated.
Is this 25 POUNDS bag of Celatom DE powder compatible with sand filters?
No, DE powder is specifically designed for DE-compatible filters; adding it to a standard sand filter can clog the laterals and cause high pressure or blowback into the pool unless you are using a very small amount as a filter aid.
Why is my pool still cloudy even after adding this 25lbs of DE powder?
If the water remains cloudy after using this 25 POUNDS bag, check for torn filter grids or a manifold crack, as even high-quality DE cannot filter water that is bypassing the media through physical gaps.
