VOLCANO STONE / AQUARIUM DECORATION
1kg/1
These stones are natural aggregates of lava of volcanic origin and therefore very light because they are exceptionally very porous. This is a good feature for the total weight on the glass of the tank, but the most important feature of these rocks is the presence of millions of micro-holes that will help the establishment of nitrifying bacteria, such as Nitrobacter and Nitrosomonas, propedeutic to aquarium development. For this reason it is also used in reduced forms as a substrate to facilitate the water flow and to make the bottom more oxygenated. Another excellent quality is also to not alter the water values.
