About the Leslie's Cellulose Fiber
LPM Part #:
Leslie's Cellulose Fiber is Safe and Natural

Leslie's Cellulose Fiber is a blend of natural cellulose fibers that replaces diatomaceous earth in pool and spa filters. In D.E. filters, Cellulose Fiber replaces the D.E. and safely cleans pool water. In cartridge and sand filters, Cellulose Fiber works as a filter aid and improves water clarity.
*6lb ships in two 3lb bags
Usage Tips
Tip 1: Shortened Cycling* with New Installations
  • Leslie's Cellulose Fiber filters smaller particles than D.E., causing the filter pressure to rise more quickly than usual for one or two cycles. During these cycles your filter is cleaning the small particles missed by D.E.
  • After the initial one or two cycles your filter's cycle time will be increased versus D.E.
    * Backwashing + recharging= cycle

Tip 2: Chemical Compatibility
  • Leslie's Cellulose Fiber has no known compatibility issues.

Tip 3: Oil Contamination
  • Oils from high-bather loads may cause Leslie's Cellulose Fiber to initially load up quicker. This is because D.E. does not filter all oils.
  • In most residential pools and spas, this will not occur due to lower-bather loads.

Tip 4: Short Cycling of Filter
  • Initial short cycling of the filter is only a sign that Leslie's Cellulose Fiber is collecting impurities from the water that were not captured by the previous filter media.
  • If short cycling persists, the water chemistry should be checked.

Tip 5: Environmentally Safe
  • Leslie's Cellulose Fiber is all-natural cellulose fiber (wood pulp).
  • Leslie's Cellulose Fiber is non-toxic and biodegradable.

Tip 6: Cartridge and Sand Filters
  • Leslie's Cellulose Fiber will also maximize your cartridge and sand filters' filtration rates. (Not necessary if already using ZeoSand in filter.)
  • Filter pressure may increase or cycle more quickly than usual due to Leslie's Cellulose Fiber's increased rate of filtration.
  • Follow manufacturers' instructions for cleaning and backwashing filters.
