DGS Dryden Glass Sand Filter Media – Grade 2 (0.8‑2.5 mm, 25 kg Bag)

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
