Robelle Diatomaceous Earth Pool Filter Powder 10.9 kg (4 x 2.72 kg) Ready-to-Use D.E., USA-Made for Clearer Water

Robelle 24-Pounds Premium D.E. is a ready-to-use diatomaceous earth pool filter powder packaged as four 6 lb charges to restore and maintain sparkling, clearer pool water.

Designed for convenience and consistent performance, this USA-made D.E. comes in a moisture-resistant box that’s easy to store and handle. Each pack includes four separate 6-pound charges, making measurement and dosing straightforward for most standard diatomaceous earth pool filters. Follow your filter manufacturer's recommended square-foot capacity, then add the correct amount of Robelle D.E. to help trap fine particles and keep pool water visually clearer between cleanings.

How much Robelle D.E. should I add to my filter?

Measure the area of your filter element in square feet (this is usually printed on the filter housing). The general guideline is 3 pounds of D.E. for every 20 square feet of filter area — use that ratio to calculate the initial charge.

• Use 3 lb D.E. per 20 sq ft of filter surface.
• Each box contains four 6 lb charges for easy partial fills.
• Check the filter housing label for the exact square-foot rating.

What is the best way to add D.E. to the pool system?

Pour the measured D.E. into the skimmer or the filter's distributor according to your filter manufacturer's instructions, with the pump running for even distribution. For routine maintenance, small daily additions can extend time between backwashes.

• Start with the recommended initial charge for your filter area.
• For pools up to about 20,000 gallons, add one full cup to the filter inlet morning and afternoon to extend cycles.
• Always operate the pump during dosing to ensure even coating of the filter element.

What should I expect after adding Robelle D.E.?

Initially, you may notice shorter filter cycles as trapped particulate and previously unfiltered material are removed; this is normal and shows the D.E. is doing its job. After the system clears those particulates, cycles should return to normal and water clarity should improve.

• Shorter cycles at first indicate heavy debris being captured.
• Regular cleaning/backwashing will preserve filter efficiency.
• Consistent dosing helps maintain clearer water over time.

How do I store and handle the D.E. safely?

Robelle D.E. is packed in a durable, moisture-resistant box for convenient handling and storage. Keep the box dry and sealed between uses and avoid inhaling dust when measuring and pouring.

• Store in a cool, dry place away from moisture.
• Use a mask when pouring to minimize dust inhalation.
• Keep out of reach of children and pets; follow local disposal rules for used D.E.

Who is this for: Robelle 24-Pounds Premium D.E. is ideal for pool owners and maintenance professionals who use standard diatomaceous earth filters and want a convenient, pre-measured supply. It suits backyard pools, seasonal users who prefer separate charges for precise dosing, and anyone seeking an American-made D.E. powder to help trap fine particles between cleanings. Always pair this product with your filter manufacturer's guidance for best results.
