    Hi all,

    I bought this 'Rainbow slate' off the internet from an aquatics online store. Having looked at it, I'm a little concerned whether it is safe or not to put in my tank any advice would be highly appreciated thanks.

    Looks like natural stone and if so should be safe, What are your concerns?

    You can try the vinegar test.

    Another option is to put the stone in a bucket of water and let it sit a few weeks. Test the water with your water test kit before adding the stone then test the water again after 2 weeks. If no change in water chemistry, it’s a good indicator the rock isn’t leaching anything.
