Vulcanic Lava Gravel is also an effective natural filter for the aquarium. If you decide to use this type of substrate, the water change in the aquarium can therefore be performed much less frequently.

Perfect for plants, because most of them take root very well in it and, additionally, the lava provides adequate oxygen access, which prevents putrefactive processes.
