Robelle diatomaceous earth powder is an all-natural, porous powder derived from the tiny fossilized exoskeletons of algae-like water plants known as diatoms. When used in D.E. filter systems, diatomaceous earth powder provides a remarkable filtration media, trapping debris and contaminant particles ranging from leaves and dirt to bacteria and other microorganisms. Fresh diatomaceous earth powder is required every time you backwash your D.E. filter and will keep your filter working at peak performance. Our multi-pack has four 6lb. easy to handle bags for convenience. Robelle D.E. filter powder is of the highest quality and will provide you with outstanding filtration results that will leave your pool water sparkling clean.

Available in a 24 lb box with two inner 12 lb bags.


Available in 10, 25, or 50 lb bags.

Robelle Pool Filter Sand is custom ground to our quality specifications to make your sand based filter system run at peak performance. The constant flow of water through a layer of sand removes any impurities in your pool water. The sand in the pool filter is cleaned regularly through a process called backwashing, which allows the sand filter to last between three and five years. After this time period, you must change out the old sand with new sand to resume providing adequate filtering.

Available in a 50 lb bag.
