Petzlifeworld 1 L Media Aqua Clay Water Filter Balls Loose Pack with net Bag (8mm)

In big ponds and aquariums the increased metabolism due to high fish populations often leads to increased water pollution. For this reason Aqua clay F-13-20 was developed.

Aqua clay F-13-20 should ideally be put in the provided filter medium bags Aqua clay F-13-20 should be washed under warm, running water before filling the filter. During the first filling of the filter the bacteria need approximately 2-4 weeks to reach about 70% of the filtration performance. After 4-6 weeks nearly 100% of the filtration performance is accomplished. The colonization time can be reduced by using bacterial cultures (bacteria starter).
