Diatomaceous Earth Filter Media is designed to filter the smallest particles out of your water, and leave your pool sparkling clear. Made from microscopic, fossilized algae, diatomaceous earth (DE) is a powder that acts as millions of tiny sponges, absorbing and trapping particles that contaminate and cloud your water. Capable of filtering out particles as small as one micron, diatomaceous earth filters are the most efficient and effective pool filters available.

Filters Down To One Micron!

Cloudy water can often come from particles too small to see refracting the light in your pool. Diatomaceous Earth is capable of filtering particles down to one micron in size, more than 100 times smaller than the average grain of sand!

Leaves Pool Water Crystal Clear

By eliminating these microscopic particles, DE filters clean and polish your pool water, making it sparkle like new.

Designed Specifically For All Pool and Spa DE Filters

Top-quality and easy to use, our Diatomaceous Earth is designed to work in all pool and spa DE filters. Changing the DE in your pool filter may sound like a challenging task, but with our Diatomaceous Earth, it couldn't be easier. Before using, it is necessary to backwash your filter. After backwashing, mix the required amount of DE in a bucket with water, until you have a thin, creamy mixture. We recommend using 1 pound of DE for every 5 feet of filter area. With the pump running, simply pour the mixture into the skimmer, and the DE will be drawn into the filter and coat the filter grids.
