    Hi friends,

    Newbie here, getting into aquascaping.

    Hope to get some help on these rocks, for using in my 90 liter aquarium...
    IMG_20150329_120611 (1).jpg IMG_20150329_120512.jpg
    About fist-size. Fizzes in vinegar (4% acetic acid) and stops after 5-10 minutes. Has little red specks like Rust (might be Iron deposit) and white patches (might be calcium)
    Has the looks of LAVA rock, but not absolutely sure..

    I am extremely tempted to use this in my aquarium. Can I use these, after immersing them in vinegar and boiling water?

    Help appreciated and thanks in advance.

    Hi Jaigu, I think the fizzing is coming from the calcium when you add the vinegar.
    Normally if rocks fizz you should not use them. Saying that i think the rock you have would be safe to use ??

    Sorry i could not be of more help :( Others will know more :)

    I have moved it for you.

    Personally I would not take the risk if there is a concern financially it might not be worth the risk.

    I always tend to be on the safe side especially when you have been given a warning.

    In all aquarium work it pays to follow a very old simple rule "If in doubt leave it out"

    These rocks are beautiful. I would have not given up on them so easily. I would suggest you to let them sit in a weak acidic solution for a couple of weeks , transfer it to normal water and then test I change in water parameters.

    Yes, beautiful they are. But I don't know what its going to leach into the water. By the way, Is pea-sized crushed ballast stones safe for use in aquarium? You know, the stuff they pulverize from the mountains in India, for mixing in concrete to construct buildings. Is it safe?

    The safest rocks are those sold by your LFS unless you know about rocks and how to test them.

    If you are referring to the grey/black rocks, they can be used.
