Pool Filter Glass Media Conversion
Calculate how much Activated Filter Glass you need when upgrading your old sand filter. Glass is lighter and more efficient than traditional silica sand.
Technical Comparison
| Filter Media | Micron Rating | Lifespan | Amount Needed (vs Sand) |
|---|---|---|---|
| Standard #20 Silica Sand | ~20-30 microns | 3-7 Years | 100% |
| Zeolite (Zeosand) | ~5 microns | 5 Years | 50% (Very light) |
| Activated Glass | ~3-5 microns | 10+ Years | 80% |
Frequently Asked Questions
Why upgrade to Glass Media?
Glass filters down to 3-5 microns (almost D.E. quality), compared to sand which only filters to 20 microns. Glass also rarely needs replacing, whereas sand calcifies every 5 years.
What happens if I overfill the glass?
If you put 300 lbs of glass into a 300 lb sand filter, the glass will end up piled higher than the sand would have been. During your first backwash, you will blow 60 lbs of expensive glass directly out into your yard.
