4024 D.E./Diatomaceous Earth Powder for Swimming Pools, 24-Pound

I liked the fact that the powder was in pre-packed into 5LB bags.

I’ve used this product for 30 years. It’s fantastic diatomaceous especially for pools works really well. Cleans does his job. Fantastic shame I’ve gotta go to America to buy it. Can’t find anybody in this country that sells it. I paid the freight and then get it on Amazon from America. I think I’m crazy but it’s worth it.

Maintaining crystal-clear pool water has become noticeably easier since switching to Robelle's premium diatomaceous earth pool filter powder. This 24-pound bag provides excellent value for the entire season, and the quality of the product translates directly to superior water clarity compared to other brands I've tried.The powder disperses smoothly through my D.E. filter system without any clumping or residue issues that I've experienced with lower-grade alternatives. The filter efficiency is noticeable—water clarity improves significantly after application, and I've noticed I need fewer total applications throughout the season. This makes the product economical in the long run, as you're getting more filtering efficiency per pound.Installation is straightforward; I simply add it through the skimmer as directed, and it integrates into the filter system efficiently. The product consistency is reliable—there's no variance batch to batch. For anyone serious about maintaining their pool, the difference between premium and standard D.E. powders becomes apparent quickly. This Robelle product delivers professional-grade results for residential pool owners. If you want your pool water looking resort-quality all season long, this premium option is worth every penny.

Great product, got it at a good price too…

I’ve been using this brand for several years and it works perfectly in my Hayward DE filter. I love the individual bags too. No more measuring out cup fulls.
