Fltr Sand, .45mm-.55mm Bx, 50lb

Filter sand graded to a 0.45mm-0.55mm range is a true workhorse media for sediment and turbidity reduction in backwashing filters and multi-media beds. Sold in a 50-lb box equal to roughly one-half cubic foot and packaged for convenient UPS shipping, this carefully sized silica sand provides a consistent, uniform particle distribution that translates into predictable, repeatable filtration performance. It is one of the most cost-effective ways to polish water and protect downstream equipment from grit and suspended debris, which is why it remains a staple in both residential and small commercial systems.

The narrow grain range makes this sand well suited as a primary filtering layer or as a component in a graded-density bed positioned beneath lighter media. Its uniformity helps establish an even flow path through the filter, trapping suspended particles while keeping pressure loss across the bed manageable. For private wells and municipal supplies alike, graded filter sand is a proven foundation for reducing the cloudiness and sediment that can clog aerators, foul appliances, and leave residue in plumbing fixtures.

Installation Tips

For long service life and consistently clear water, layer the filter sand over an appropriate gravel underbed that protects the distributor laterals and ensures even flow across the full diameter of the tank. After loading, backwash the bed thoroughly at start-up to flush out the lightest fines and classify the sand into stable, well-ordered layers. Then verify that your backwash flow rate is sufficient to fully fluidize and clean the media during each regeneration cycle, since under-backwashing can allow the bed to pack and channel over time. Properly sized for your flow rate, supported with the right gravel, and maintained on a regular schedule, graded filter sand delivers years of dependable, low-turbidity water for the whole household. Periodically checking that the bed remains level and unconsolidated, and increasing backwash frequency during periods of heavy sediment load, helps the sand keep delivering clear, low-turbidity water without packing or channeling over its long service life.
