Achieve crystal-clear, perfectly purified water in your pool with high-purity, high-porosity Diatomaceous Earth in a 22.7 kg format (Reference: BA117734). This natural filter medium is the ultimate solution for homeowners seeking superior performance from their filtration systems, far surpassing the effectiveness of traditional silica sand or conventional filter glass.

Thanks to its unique microscopic structure, composed of fossilized algae, this filter powder acts as an extremely fine mesh capable of retaining microscopic particles that other filters allow to pass through. The result is visibly clearer, cleaner, and impurity-free water, drastically reducing the need for large quantities of chemicals for daily pool maintenance.

Main Features

• High degree of purity: Rigorously selected to ensure optimal performance in the filtration of residential and commercial swimming pools.


• Advanced porosity: Its porous structure creates millions of microchannels that trap even the finest dirt, such as dust, microscopic algae, and body oils.


• Professional format of 22.7 kg: Ideal quantity for loading and periodic refilling of the filter, ensuring long durability and efficiency.


• Chemical savings: By retaining a greater amount of suspended particles, it optimizes the action of chlorine and other disinfectants.


• Ecological filter media: A product of natural origin that improves the sustainability of your pool maintenance.

Frequently Asked Questions

How do you add diatomaceous earth to the pool filter?

Once the filter has been cleaned or backwashed, mix the recommended amount of diatomaceous earth with water in a bucket until you have a homogeneous mixture (slurry). Slowly pour this mixture through the skimmer with the filter running so that it is evenly distributed over the filter elements.

How often should this filter medium be replaced?

Diatomaceous earth is discarded each time the filter is backwashed. Therefore, you will need to add a fresh dose of the product each time you clean the filter due to dirt buildup, which will depend on usage and the pool's environmental conditions.

Is it compatible with any type of pool filter?

No, this product is specifically designed for use in diatomaceous earth filters. It should not be used in traditional sand filters or conventional cartridge filters, as the retention system and water flow require a specific grid structure for this type of media.

What advantages does it offer compared to silica sand?

The main advantage is its filtration capacity. While sand filters particles down to 20-40 microns, diatomaceous earth can retain particles between 1 and 3 microns. This results in much clearer water and a significant reduction in the consumption of maintenance chemicals.
