Filter media and UVC
Two different filter sponges, as well as bio-surface elements and filter pebbles, ensure mechanical and biological cleaning. 7/11 watt UVC power for clear and healthy water.
Bio-cores and filter pebbles
The filter pebbles in the net bag and the bio surface elements offer adequate settling surface for the micro-organisms.
The UVC bulbs should be changed at regular intervals, ideally in spring before the season starts, to guarantee the full strength of the UVC light!
