 Use for trickling.

A) Prolong the connecting time between stream, air andnitrobacteria on the surface of balls.Improvethe filtering effect and oxygen-dissolved.(The anaerobic case also uses bio-chemical balls to prolong the connecting timebetween stream and anaerobic bacteria.)

B) It is made from hard and smooth plastic,which is different from porous filters.There will be a special velum on the sruface after using a period of time (I takes  long time to form a velum). When the velum perishes, it will drop off along stream autonmatically and be replaced by a new-bornvelum.This process is called Self-purification.(It is better to add physical white cotton on top of the trickle filter groove.)
