INCLUDES FREE DELIVERY!SUSTAINABLE, EFFICIENT, AND SUPERIOR FILTRATION - Our Glass Filter Media is crafted from 100% recycled glass, ensuring no material is left behind. Unlike some filtration products made from virgin glass, which increase the demand for quarried materials, our media uses fully recycled glass, contributing to a circular economy and minimising environmental impact.AQUARIUM FRIENDLY - Ideal for freshwater and marine aquariums, our glass media provides a stable foundation for aquatic plants and a safe habitat for fish and invertebrates. It won’t alter water chemistry, ensuring a healthy and balanced aquatic environment. This smooth, eco-friendly substrate is perfect for creating a natural-looking and low-maintenance aquarium or pond floor.BENEFITS - Our media is safe and free from sharp edges, making it easy to handle. Produced entirely from post-consumer soda-lime-silica glass, our media is a sustainable choice. The smoother surface of our glass particles prevents bacteria from getting trapped in cracks or flaws, reducing the need for chemical treatments and remedial actions. Less dense than sand, our media requires 15% less material to fill an equivalent filter.PERFORMANCE - With 30% smaller head loss development compared to sand, backwashing is quicker and less frequent, saving time, energy, and money. The angular to sub-angular particle shape and bound silica content provide a 30% improvement in turbidity removal over silica sand.PROPERTIES AND COMPLIANCE - Made from 100% recycled post-consumer glass, processed to ensure safety and effectiveness.
