Bag vulca pozzolan 3kg for aquarium special plants.

Vulca is a pozzolan soil, a natural volcanic rock with a honeycomb structure.

Grain size 7/15 mm.

Thanks to its natural porosity, it allows a good circulation of water in the soil and thus favors the development of bacteria and the rooting of plants.

It is particularly appreciated in aquascaping because it allows to stabilize the soil under decorations like rocks or roots.

It is ideal for use under gravel so as not to harm bottom fish.
