U.S. Silica Mystic White II Sand

High-Quality Filtration: U.S. Silica Mystic White II Pool Filter Sand provides superior filtration for both above-ground and inground pools. This 50-pound bag delivers high-purity white silica sand designed for consistent performance with sand filter pumps.
Convenient Packaging: Available in packs and bags, making storage and handling straightforward for homeowners and service technicians alike. This sand is formulated to integrate smoothly with most standard sand filter systems.
Effective and Reliable: The sand features uniform grain size to help trap dirt, leaves, oil, cosmetics, gum, and other debris, contributing to clearer pool water and less frequent backwashing when paired with proper maintenance.
Palmetto Pool Filter Sand

Crystal Clear Pool Water: Palmetto Pool Filter Sand effectively captures leaves, dirt, dust, sunscreen oil, hair, and other small particles, helping pools stay pristine across the season.
Superior Purity: Undergoes a rigorous washing and screening process to provide pure sand with a reliable 20-40 sieve range, supporting cleaner water and reduced maintenance time.
Safe and Natural Composition: Soft, clean sand free from harsh additives, meeting standard requirements for most filter pump brands to ensure safe operation and healthy swimming.
OptiFlow Pool Filter Sand

High-Power Filtration: OptiFlow uses a pure silica formula to trap dirt and debris, promoting crystal-clear pool water and a pristine swimming environment.

Easy to Use and Maintain: The balls are reusable; rinse and clean to restore filtration performance, reducing the need for frequent media replacement.
Buying Guide: Key Considerations for Filter Media Selection
- Filtration performance: Sand media with uniform grain size provides reliable filtration for general pools, while filter balls can capture smaller particles (microns) and may improve water clarity with lower backwashing frequency.
- Media type and lifecycle: Traditional silica sand is durable and widely compatible, but filter balls offer significant weight savings, easier handling, and reusability, which can reduce long-term maintenance.
- Pool size and system compatibility: Larger inground or high-flow systems may benefit from media with higher flow characteristics and larger media grain patterns; confirm compatibility with your pump’s valve and tank size.
- Backwashing and water use: Filter balls typically reduce backwash requirements and water waste. Sand, while effective, may require more frequent backwashing depending on particulate load and pool usage.
- Maintenance and cleaning: Reusable media like filter balls allows for washing and reuse, which can lower ongoing costs. Sand media generally needs periodic replacement after extended use.
- Environmental considerations: Eco-friendly options exist among filter balls and alternative media; consider lifecycle impact and disposal when selecting media.
When choosing media, align your choice with pool size, water chemistry, and maintenance goals. For many residential pools, a combination approach—using high-quality silica sand for overall filtration and filter balls for specific high-load scenarios—can offer balanced performance and cost efficiency.
