Filtration with Glass Media
Zodiac Filter Crystals are made from 100% recycled clear glass and are part of what makes MagnaPool® special. The crystals are a type of pool filter media that act as a direct replacement for sand or zeolite. Sand filtration, although very popular, does have many limitations, such as potentially harmful bacteria growth, inefficient backwashing and additional strain on the sanitiser.
The smooth surface of Zodiac glass crystals discourages bacteria from attaching to the glass. This results in a healthier filter tank, that is safer for you and your family. When compared to regular sand, glass crystals can save up to 65% of water through more efficient backwashing. This is due to the larger spaces between the particles which allows for a more efficient water flow. Zodiac Crystallite filter media is available in two grades, fine and coarse – and you need both grades to experience the difference with a MagnaPool®.
Glass media filtration increases energy efficiency as well as provides sanitary and environmental benefits over using sand or zeolite.
In the filter, the coarse crystals are placed at the bottom to reduce any clogging issues, then the fine crystals are placed on top. This set up provides the most efficient way for water to circulate through the filter tank. As glass media filtration is less prone to clogging, your pool water will be filtered more efficiently.
When it comes to the flow rate of water via your pool’s filter, the crystals allow more water to be circulated throughout the hour, which translates into more energy savings for you.
Efficient Water Usage
Did you know that using crystals can save you up to 65% of water? This is due to the fact that there is more space between the glass media (than when using sand), which allows water to flow more efficiently. This means the need to backwash is greatly reduced. In fact some MagnaPool® owners can go entire seasons without the need to backwash their filter.
Sand is more prone to housing harmful bacteria especially when housed in a poorly maintained sand filter. The unique smooth surface of the crystals discourages bacteria from attaching itself to the glass, unlike sand, and provides you and your family a healthier pool to swim in and enjoy.
