Brand

Clean, consistent water depends on filtration media that performs reliably under continuous flow, and U.S. Silica Silurian pool filter sand is processed to support that outcome across residential and commercial outdoor pool systems. Developed with controlled silica grading, this pool filter sand delivers stable filtration performance across pump-driven swimming pool and home backyard spa setups. 

Each grain is sized to a 20-grade range, helping maintain balanced flow while capturing fine debris that contribute to cloudy pool water. The uniform particle size is carefully screened to reduce channeling inside the filter tank, allowing water to pass evenly through the media for improved contact and more effective debris removal during cleaning cycles. Consistent grain distribution also supports stable filter bed pressure, reducing strain on pump systems during high-demand circulation. 

The angular structure increases surface interaction, helping trap dirt, oils, algae particles, and suspended sediment during filtration. This supports consistent water clarity across inground pools, above ground pools, and sand filter pump systems used for routine pool cleaning. The angular grain geometry also extends media life between full sand replacement cycles. 

Its chemically inert silica composition functions alongside chlorine tablets, algaecides, and pH balancers without affecting water balance or degrading under chemical exposure. This supports stable operation across freshwater pools, saltwater pool systems, and spa filtration setups through continuous seasonal use. 

Compatible with multiport valve configurations and variable speed pump setups, the 50-pound bag covers full filter replacement or scheduled media changes in most residential filter housings. U.S. Silica Silurian filtration sand integrates cleanly into existing pool filter systems, pool pumps, and outdoor pool maintenance routines without additional adjustments.

Great value

Worked for what I needed

[This review was collected as part of a promotion.] very easy to put in our new sand pump

[This review was collected as part of a promotion.] Great option for sand filter!

seems to be working great in the new pool pump.

[This review was collected as part of a promotion.] the product itself is unharmed, but theres less of it than there was supposed to be. it was more affordable than other sand. frankly i dont see how they could do sand poorly even if they tried.

bag came torn and taped.. thus leaking.

Product it's fine. It's Walmart. That sucks.
