How it works:
One of the newest filter media on the market, Glass Pearls offer a filtration level comparable to DE. Made from pure glass, the Glass Pearls filter out anything larger than 3 microns, giving you superior quality water.
Small effective size of only 0.6mm to 0.8mm. Its narrow particle size range allows very effective in-depth filtration
- Spherical shape of beads means less friction levels inside the filter and therefore requiring only 20% of the water you would use to backwash a sand filter
- Chemically inert, safe, smooth and high purity
- Still requires backwashing occasionally
- More costly than sand and Zeoplus
