Crystal Clear, the medium made of glass
crystals providing ultra-fine filtration and preventing the formation of biofilm (bacterial growth) in the filter.
Crystal Clear is specifically designed for the Zodiac® Boreal filter.
Crystal Clear can also be used in other types of media filter (commonly known as “sand filters").
Crystal Clear is available in 2 particle sizes (coarse and fine) which should be used together in the filter.
Crystal Clear filtration glass is manufactured exclusively from pure translucent recycled glass.
More efficient than normal sand, Crystal Clear provides a filtration rating below 20 µm in comparison to sand filtration at about 50 µm. Water circulates easily through this filter, enabling faster cleaning.
Compared with sand, Crystal Clear provides water savings up to 75% when washing the filter.
This is due to the natural absorptive capacity of Crystal Clear glass, enabling "volume" filtration (as opposed to "surface" filtration with sand). When washing the filter, particles are more easily detached from the glass, making washing cycles shorter.
