Hello, we just replaced the sand filters with recycled glass from GACHES (GAROfiltre). This filter media is worth looking into for the following
reasons: - Finer particles = diatoms filters of less than 15 microns vs 40 microns for sand, - significant reduction in pressure losses,
(especially if the glass filter is used in conjunction with variable speed circulation) - Reduction of chloramines - Reduced number of washes
(because less clumping compared to sand) - 100% recycled and 100% recyclable material.
