Trap Even the Smallest Particles With D.E. & Perlite Filter Media


Get unmatched water clarity using high-performance filter media designed for D.E. pool filters. Our 4-pack of 6 lb Diatomaceous Earth (D.E.) bags delivers fine filtration down to 2–5 microns—ideal for maintaining crystal-clear water. Prefer a low-dust, eco-friendly option? Try our 12.5 lb bag of Perlite filter media, a lightweight, efficient alternative to traditional D.E. powder. Whether you're topping off or doing a full recharge, both options help your filter run at peak performance.

Support Your Filter With Shock & Algaecide

While your D.E. filter handles physical debris, pool shock and algaecide target what filtration alone can’t—like bacteria, organic contaminants, and algae growth. Keep your water sanitary and sparkling by pairing routine filtration with weekly chemical treatments. Explore our selection of fast-dissolving shock and algae prevention chemicals to complete your pool care routine.

Frequently Asked Questions

How much DE powder should I add after backwashing or fully cleaning my filter grids?
After backwashing, use about 80% of the recommended DE amount; after a full grid cleaning, use 100%. Check your filter’s label for exact measurements. For DE and other filter media, visit our filter media collection.
How and where should I add DE powder to my pool filter?
Mix DE powder with water in a bucket to create a slurry, then pour it slowly into the pool skimmer while the pump is running. This allows the DE to coat the internal grids evenly.
How do I make sure my pool water stays safe with a DE filter?
Test for pH, chlorine, and alkalinity at least weekly. Your filter removes particles, but safe, clear water also requires good chemistry. Find reliable test kits from Taylor in our pool water testing collection.
Do I need a chlorinator with my DE pool filter?
A chlorinator works with your DE filter to control bacteria and algae by automatically sanitizing your pool water. For best results, browse the options our collection of pool chlorinators.
Why does adding DE powder make my pool cloudy?
Cloudy water after adding DE usually means torn or damaged filter grids, allowing DE powder to return to the pool. Inspect and replace any worn grids to restore proper filtration.
