Lava 20-40mm 20kg

Lava is a mineral-rich volcanic natural rock with a grain size of 20-40mm. Lava is used in aquariums and gardens due to its open shape and dark color.

Valuable trace elements support the growth of plants in aquariums.

In the garden, lava protects the soil from drying out, retains heat from the sun and provides good soil ventilation.

Usage:

- in the construction of ponds and reservoirs for good formation of plant roots
- as a filter material in filters for natural and swimming ponds (bioplato)
- as an additive in pots for cacti, bonsai and other plants
- for ventilation and moisture storage

Color: brown-red
