Re: Can these rocks be used
Khangers also contain metals and not good for the health of fishes/invertebrates. So It is good to not use in aquarium. You can buy rocks from Meharuli Road to use in Aquarium.

Re: Can these rocks be used
Rajivji, thanks for the fast reply. Hmm ok will not risk using this. I thought it might be substituted for lava rocks. I was thinking of using it to raise the substrate depth for a hill look. Can you suggest me some ideas. Thanks
