No. 8 Pea Gravel Filter Support Media | 1/4" x 1/8" | 50 lb Bag

No. 8 Pea Gravel Filter Support Media is coarse filtration-support media designed for compatible swimming pool sand filters that require a gravel support layer beneath the primary filtration media. This listing is for one 50 lb bag of No. 8 support gravel with particle sizing of approximately 1/8 inch to 1/4 inch.

The gravel forms the lower support layer of the filter media bed, helping stabilize the finer filtration sand above it while promoting proper water distribution through compatible filter internals. It should only be used in filters whose manufacturer specifically calls for a gravel support layer.

Important Ordering Information

This listing is for one 50 lb bag of No. 8 filter support gravel sized approximately 1/8" to 1/4".

This is support gravel, not No. 20 filtration sand. Confirm your filter manufacturer's required media type, particle size, and total gravel weight before ordering.

What Is No. 8 Pea Gravel Used for in a Pool Filter?

No. 8 pea gravel is used as a support layer in certain layered sand-filter media beds. Rather than serving as the primary filtration material, the coarse gravel is installed at the bottom of the filter beneath the finer sand.

In filters engineered for this type of media configuration, the support gravel helps maintain the proper media-bed structure and protects the lower distribution area from being packed directly with finer filtration sand.

Why the Correct Support Media Matters

Supports the Media Bed
Creates the coarse lower layer required by compatible multi-layer sand-filter designs.
Maintains Proper Layering
Helps keep finer filtration sand positioned above the lower filter support and distribution area.
Sized for Support Applications
No. 8 pea gravel uses a substantially coarser particle size than standard pool filter sand.
Check Your Filter Manual Before Ordering
Not every swimming pool sand filter uses a gravel support layer. Some filters are designed to be filled only with the specified filtration sand or another approved media. Always follow the media-loading specifications for your exact filter model.

Compatibility & Filter Requirements

No. 8 support gravel should only be used in a filter whose manufacturer specifies a coarse gravel support layer beneath the filtration media.

Before ordering, verify all of the following:

  • Your filter requires a gravel support layer.
  • The specified gravel grade or particle size matches approximately 1/8" to 1/4".
  • The required total gravel weight matches the number of bags being ordered.
  • The gravel is installed in the correct layer of the media bed.
  • The primary filtration media is loaded according to the filter manufacturer's instructions.
Installation & Media Loading Guidance

Always follow the media-loading instructions supplied with the specific filter. Gravel requirements can differ significantly between filter models and sizes.

  • Shut the filtration system down before servicing the filter.
  • Drain and open the filter according to the manufacturer's service instructions.
  • Inspect the filter's internal laterals or distribution components before adding media.
  • Add the specified quantity of support gravel as the lower media layer.
  • Level the support layer without damaging internal components.
  • Add the required filtration sand or other approved media above the gravel layer.
  • Return the filter to service using the manufacturer's startup and backwash procedure.
No. 8 Gravel vs. Pool Filter Sand

No. 8 pea gravel is not a substitute for standard pool filter sand. The two materials serve different purposes within filters designed for layered media.

No. 8 Support Gravel Coarse lower support layer beneath filtration media
Pool Filter Sand Finer primary filtration media used to capture suspended contaminants
