How to Change Sand in Bestway Pool Filter

In this video, we walk through the complete process of replacing the filter media in an above-ground pool system. I happen to be transitioning from synthetic filter balls (polysphere) to #20 grade silica sand.

This is a practical tutorial grounded in firsthand observation and technical clarity.

Topics Covered:
• How to determine when filter sand needs replacement (2–4 year guideline)
• Physical and chemical mechanisms that degrade sand performance (abrasion, surface fouling)
• Tools and materials required for the changeover
• Detailed instructions for draining, cleaning, and refilling the filter
• Initial backwash and rinse procedures to stabilize the new media
• Operating pressure reference post-installation (expected PSI range)
