Since it ismade from 100% recycled soda-lime glass, it also delivers cleaner water, fasterflow and less maintenance. On top of that, buying the 2 pack costs less thanbuying two single bags.WHY CHOOSE THE GLASS FILTER MEDIA 2 PACK OVER SAND? * Clearer water: First of all, glass traps finer particles than sand, so your water stays sparkling. * No channelling or clumping: Because the smooth granules resist compaction, water flows evenly through the whole filter bed for years. * Lower chemical costs: Similarly, glass resists bio-film and bacteria build-up. Consequently, you use less chlorine and flocculant. * Quicker backwashing: In addition, shorter backwash cycles save both water and electricity. * Longer life: Moreover, it lasts up to 6 years, roughly three times longer than silica sand. * Silica-free: Because it contains no crystalline silica, it is safer to handle when you change your media. * Eco-friendly: Also, recycled glass keeps waste out of landfill and supports a circular economy.PERFORMANCE BENEFITSBecause the glass filter media 2 pack keeps its shape, it maintains high flowrates with minimal pump strain.
