LACA ROCKS #5 BITS

LAVA ROCKS #5 LAVA ROCK , POROUS STONE: 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 moestablishment 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. Lava rocks are covered by holes and pores that have beneficial bacteria, which is called denitrifying bacteria. These bacteria can help in keeping normal nitrogen cycles in your aquarium. These bacteria help break nitrate to form oxygen and nitrogen and help your fish grow in a cleaner and much healthier environment.
