Can Diatomaceous Earth be used to increase efficiency of sand filter?

Yes, diatomaceous earth (DE) can be used to enhance the efficiency of sand filters in Swimming Pools and other filtration systems. When added to a sand filter, DE coats the sand particles, increasing the filter's surface area and improving its ability to trap smaller particles and contaminants. This can lead to clearer water and more efficient filtration. However, it's important to follow manufacturer guidelines for the appropriate amount of DE to use to avoid overloading the system.
