You should never run a sand filter without any filter media as it won't filter water and can damage equipment. However, you can temporarily use alternative media like filter glass, zeolite, or even emergency solutions while waiting for sand replacement.

When a sand filter runs out of media, immediate action is critical. Never operate a filter without proper filtration media.
Recycled filter glass offers superior filtration, capturing particles down to 10-20 microns compared to traditional sand's 20-25 microns. Recommended amount is typically 15-20% less by weight than standard sand. Consult manufacturer guidelines for precise measurements.
Zeolite provides enhanced filtration (5-10 micron range) with additional ammonia reduction. Replace media pound-for-pound with manufacturer recommendations.
Modern alternative with fine filtration capabilities. Typically used at a reduced volume ratio compared to sand.
WARNING: No improvised filtration method substitutes for proper filter media. Consult a professional pool technician immediately if filter media is completely depleted.
Always shut off the pump, turn the multiport valve to 'closed' or 'winterize' position, and release system pressure before opening the filter tank. Dispose of old filter media according to local environmental regulations. Follow manufacturer-specific installation procedures and safety guidelines.
