Lav 1L

Natural volcanic rock for biological filtration

EHEIM LAV consists of volcanic rock and is a natural product. Its rough, highly porous surface structure provides the purification bacteria with very good colonisation conditions. Because it is a natural product the granulate and small pieces in the packs are of different sizes.

EHEIM LAV can be washed and reused. It is suitable for fresh and marine water.
