This can translate to less pump run time and less sanitizer needed to keep the water clean and clear.How often should I change the DE in my pool filter?
Diatomaceous Earth (D.E.) Filter The D.E. needs to be replenished once the filter is turned back on. Every three months the filter should be taken apart, the grids should be hosed off, and visually inspected for any rips or tears that will cause D.E. to blow back into the pool.
