[ALWAYS IN STOCK] High Quality Black Lava Rock per kg

Description

Black Lava is of volcanic origin, featuring a porous texture, making it very lightweight and versatile. Due to its comparably low weight, it is possible to create large structures with it.


For example it is possible to design a “Green Reef”. Green Reefs are tall scapes covered in various epiphytes like ferns of the genus Microsorum or Bolbitis, Pogostemon helferi or different kinds of moss. Their roots will find a good foothold due to the porouse sctructure of the stone. Individual stones can still be moved or exchanged later on, making the layout modular.

Also a classical Iwagumi can be made from Black Lava since the very dark colours make for a good contrast to the grey color of the more commonly used kinds of stone. As an advantage Black Lava does not increase the hardness of the tank water.

Lava rock is often used in conjunction with roots. The individual stones can be covered with moss to form forest-inspired scapes.

Do you know that Black Lava is also used in different settings and not for aquarium uses as well? We have had people using this for Fijian Ground Cooking to people using it as a filtration.

Why does ot look like concrete? 

High quality black lava does look like concrete at times. At there unwashed state they do have a greyish tinge that looks like concrete.

Concrete however turns to dust and pure concrete is very brittle.

A lot of our customers may initially get disappointed as our pieces do come unwashed or they are dissatisfied with that one piece. 

We always advise our customers is if the pieces looks too big or they need to break it down,  a chisel and a hammer will break it down nicely. 

Of course if you need our assistance then simply send a message and we can assist you with your enquiry.

If you need more then 5kg, this will be a bulk order and you will be quoted separately.

PLEASE NOTE THAT WE WILL DO OUR BEST TO PICK THE PIECES FOR YOU. PLEASE BE SPECIFIC IN YOUR REQUEST ON THE NOTES.

    Live Arrival & Ordering FAQ

    Do you offer a live arrival guarantee?

    Yes. All livestock is covered by our Live Arrival Guarantee.

    In the rare event of DOA, please contact us promptly with clear photos of the livestock in the original unopened bag.

    Please review our full DOA and store policies before purchase.

    Can you ship to all states in Australia?

    No. Due to state restrictions, we cannot ship livestock or live plants to WA and TAS.

    What should I check before ordering?

    Before placing an order, make sure:

    • Your tank is fully cycled and stable
    • Your aquarium has enough space for the species
    • Your current livestock are compatible in temperament, size, and requirements
    • Your water parameters, habitat, and temperature suit the species
    • You are not adding too many fish at once
    What should I expect when my fish arrives?

    It is normal for fish, shrimp, or snails to look pale, stressed, or less active after shipping.

    This is temporary. Most livestock will settle and regain colour within a few days.

    How long does it take for fish to settle in?

    Most livestock will take 3–7 days to fully adjust to their new environment.

    Should I feed my fish immediately after arrival?

    No. We recommend waiting 24 hours before feeding to allow them to settle.

    If you already have fish in your tank, feeding them before introducing new arrivals can help reduce stress.

    Why do fish sometimes struggle after being added to a tank?

    In most cases, issues are caused by tank conditions, not shipping.

    • Uncycled or unstable tanks
    • Poor water parameters
    • Overstocking
    • Unsuitable tank mates
    What is Nano Tanks Australia’s main tip for new livestock?

    Most livestock losses happen in immature or unstable tanks, not during shipping.

    If your setup is not fully established, the risk to new arrivals is significantly higher.

    Not sure if this fish is right for your setup?

    If you are unsure whether this species suits your setup, contact us before ordering and we’ll help point you in the right direction.
