DGS Grade 2 is an advanced, eco‑friendly filter medium made from 100 % recycled glass, engineered to provide superior mechanical filtration in pool and water treatment systems. With clean, angular glass granules between 0.8 and 2.5 mm, this Grade 2 sand delivers finer particulate capture than standard silica sand. The 25‑kg bag is sufficient for a full sand‑filter media charge or replacement, offering long‑lasting performance and reduced maintenance.

• Key Features

• Glass grain size: 0.8‑2.5 mm
• 25 kg bag of recycled glass media
• Bulk bed density approximately 1.25 kg/L
• High hardness (> 7 Mohs) for durable performance
• Low impurity levels: loose organics ~95 g/ton, ferrous metal ~13 g/ton
• High sphericity (> 0.79); coefficient of uniformity < 1.85
• Effective size ~ 0.40 mm; aspect ratio ~ 2‑2.4

✓ Benefits

✓ Filters up to 30 % more particles than traditional sand, enhancing water clarity
✓ Reduced formation of chloramines and odors in pool water
✓ Shorter, slower backwash cycles compared to silica sand—saves water
✓ Less efficiency loss over full filtration cycles; longer lifespan
✓ Safer for swimmers and equipment due to purity and stable chemical behaviour
