High quality Filter material (media) ------ Active Bio Quartz Ring (ABQR)
ABQR is sintered by Quartz Sand under the condition of high temperature. The chemistry nature of ABQR is very stable. It is innocuous for the fish and aqua-plants. ABQR is the porous quartz ring which secures proper water circulation and penetration for the organic materials. It is very absorbent. It creates an ideal condition for the bacterial activity includes nitrification and denitrification. The nitrification occurs on the surface of ABQR and the denitrification occurs on the interior place of ABQR.
It is proved from many tests that:
Effect of 1Liter ABQR equals that of 15L Active Carbon and equals that of 34 Ceramic Ring and equals that of 700L Bio Ball.
