"Zelbrite": special sand of volcanic origin with filtration properties up to 1 micron.
Sacks of 15 kg. (corresponding to 20 kg. of quartz sand)
This is a natural filtration material with a porous structure allowing not only mechanical filtration but also the absorption of polluting elements as well as the ionic exchange of ammonia cation, calcium and magnesium.
This leads to a reduced use of chlorine, flocculant agents are not necessary anymore and the quantity of ammonia is also reduced.
 "Zelbrite" can be regenerated at the end of the season with water and cooking salt.
