Vitro Sphere Nano 0.40-1.20mm - 20 kg

Vitrosphere Nano Glass & bdquo; perly & ldquo; With a special treatment (made nanotechnologies) showing even very minor impurities, which significantly reduces the consumption of pool chemistry. Their round shape ensures uniform water flow by filtration, which increases the efficiency of filtration. Thanks to its special surface, dirt is perfectly separated from the filter medium when the dirt is retrospective, so the entire washing process will take place very quickly and efficiently using a minimum amount of water, saving heating costs and pool chemistry. The glass does not suffer from waterway overgrowth. & nbsp; these & bdquo; perly & ldquo; They are very hard, which guarantees their low wear and long life. & nbsp; recommended exchange of 5-8 years. & nbsp; The consumption of the filter material is lower compared to filter sand, therefore the following recalculation coefficient is recommended: 2 packaging of filter sand á 25 kg (approx. 50 kg) = 2 & nbsp; Vitrosphere package package (approx. 37.5 kg).
