Product Information

The coarse structure of the chemically purified pieces of filter lava makes them particularly suitable as biological filter substrate in all kinds of pond filters. In the many pores of the porous material, many billions of micro-organisms will develop, whereby an ideal filtering of the pond water takes place.

Lava Rock contains a range of chemical elements including magnesium, calcium, iron potassium and manganese. This type of rock is characterised by its low weight compared to its volume.
