Vulcanic Lava Coarse Gravel/substrate is a choice for people who value original arrangements. It is distinguished by interesting shades. It is also rich in micro and macro elements that can positively affect the ecosystem of the entire aquarium.
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.
It does not change the water parameters and is completely indifferent.
Safe for all living organisms, perfect for shrimps and bottom fish.
It does not affect the water parameters and does not change the gH, kH, and pH values
Size of the bag: 5l

We recommend rinsing the substrate before use. After pouring it into the aquarium and flooding it with water, turbidity may appear, which will disappear over time after starting the filtration.
