Dryden Aqua AFM Glass Filtration Media 0,25-0,5mm (Grade 0)(25kg)

Replaces sand in all filtration applications. AFM® is manufactured from a specific glass type and processed to obtain the optimum particle size and shape. It is then activated to increase the surface area by 300 times over crushed glass or sand.
The high surface area is negatively charged (zeta potential) to adsorb organics and small particles. It also has permanent metal oxide catalysts creating a high redox potential to make AFM® self-sterilizing.
AFM® is the only activated glass filter media available, and is more efficient and cost-effective than any other filtration media. AFM® is certified under Regulation 31 in the UK and International NSF61.It is also in compliance with European Water Directive (98/83/EC) & (80/778/EEC).
